You are having him buckle at the knees here and there and what we need is to have him rocking on the toes and heels and if anything straightening his legs out more and pivoting at the hip. Like at frame 80 he seems a little pinned at the hip and his knees are just moving around.
Angle his head toward the door. Curve the spine the other way.
Close his fingers up a little bit more. There is something about the way his hands are there. He should be holding one hand in the other and it just drops naturally. It still feels like they are help up a little bit and the fingers are splayed a little bit wierd and it seems like.
What we were talking about before was him coming down in this anticipation and then coming more forward. Keep his eyes up and keep his focus almost like he is speaking to someone back there because he is.
Avoid him slipping off model with his jaws. It looks like his entire jaw is hanging down a bit. He slips off model.
Again your hands are very palm up. It look like the thumbs are broken out a little bit and they are very palm up and I would get them three quarters facing into him and maybe even angled a little bit more are him at the wrist.

This definitely working better. I th still think you are moving him too much for this beginning part.
When you turn him so far away from us I would rather it stay in the realm of where it is at the beginning and when you really want to emphasise that he is talking to someone through the door you could lean his head more instead of actually face the door.
His tors also has got really short and his legs very long!
Make sure also that you are not getting wierd bends. There is some sort of wierd bend at the top of his spine. Also change the lighting.
You need just smaller movements. Just basic smaller head nods. A tad of reaction to those in the body. He is also raising his hands behind his body a lot and that is a lot of work to do. They would pretty much be at rest and they would respond to hip movement but he is mot acting with them at that point.
Then at the end when he freaks out it feels a little wierd when his legs are so together and he goes down. You could use something like that as an anticipation maybe but I think that I would try to almost get a nice sweeping line of action with his chest forward and his head would probably be angled downward so he is looking up his brow at the door so that it is almost like a diagonal line from his feet up to his head.
His hands are not as stong as they could be. They need to be more claw-like. He is so angry at that point. I would really get those angles in his fingers, if you have to shoot more reference, check out hand poses, really get those hands working and make sure you are doing all you can to get some nice silhouette and not just clumping over the body like that.
Something with his hands down mught even work. You could experiemtn with that but really make it a lot more rigid and a lot more strong and just simplify the beginning even more.

I did not mean him actually completing an action. I just meant he is not just randomly sleeping in a chair so that he was just watching TV and falling asleep. You could start the shot with him already fallen asleep. This scenario would be fine if he is just asleep in the chair because people sleep at their desks all the time.
I think with your sleeping pose I would try to get it so that he is a little bit more relaxed like if you turn the chair towards the computer screen and we see the spine more kind of like if he is slouched in the chair and maybe his arms are kind of folded and his legs maybe even crossed and I think while he is sleeping there would not be as much movement as you have in his body. Certainly not tapping his toe. It feels like he has hurt his neck this way laying in the chair for too long. It feels like he is listening to music because he is tapping his toe and he has got his shoulders going so if you can scale the chest and spine I would just have a heave of breathing there and maybe a slight reaction in his head to the breathing but it would be very subtle there.
The mosquito is probably too big. It does not have to be totally identifiable as a mosquito to us. We dont need to put it on a microscope. Even if it is a dot zipping around we know it is something that is going to get on him and hurt him and his reaction is going to be all the clarity we need. So I would make that a lot smaller and almost like a dot coming around and then when you go to break this down - it is flashing. Just make sure you have got the separate actions. Right now you have got him coming up and his hand coming up at the same time and the way it is coming up almost flashes like he is waving at the bug already so I probably would have him come up at least for a quick beat and then smack his neck quickly. If something was happening you would find the quickest path to it and not anticipate it that much. I dont think you need to have him drop his hand and then slump back down. Its ok that the mosquito comes off but once you make it that small....like right now he is looking him like taunting him because he missed killing him but once its that small you are not going to be able to see that kind of thing so we are assuming he is dead the mosquito and he could almost stay in that position or we could just look at his hand but not as big a change we are like changing into a whole different beat and I dont think I would do that. I would just concentrate on making the ones that are pertinent to the shot really work.

The idea will work but you need to think about where this guy is when he fell asleep. But if he was sitting in a chair watching TV then maybe he would not be sitting so upright like that so think about that in your pose before you start blocking that out. Then the relaxed pose is working but the frantic is not coming across. I think that the alarm of him being stung by something all of a sudden is reading but you dont need to have him come to his feet like that. Its not reading off the bat like something hit his neck. You could have him back and he has his arms and his legs crossed while he is sleeping and then all of a sudden his eyes open and he scrambles quick and then he slaps his neck. He uncrosses his feet his legs. He is back sleeping and then hits his neck. You also dont need to overdo this swiping down or anything. Just bam and then checking out whatever did that to him. I think they will be a little bit quicker reads and a lot of it is going to be sold in the facial. If you can get the mosquito or fly or whatever you are going to use, that would be good too. Your sketches are really thorough. I think those poses I would probably change and just make sure you really sell the facial. However you do the start of being stung all of a sudden. I dont think you need to play it as long as you are when you stand up and then go. I think even if you dont scramble just go to the hit. I would not take so long because that impulse to your brain, there is something causing pain to my neck, boom I am going to find out what it is. It just would not take that long. Its looking good.
