Point blank Headshot

the butt of the gun should be against his shoulder and the kickback looks a little wierd, also at that range the guy who got shot would have gone flying back but the fall looks nice so ill let that slide ;) the part where the arm falls at the end needs some more easing, also the blood should spurt some but the blood on his face looks nice even though it moves around some, all in all its a nice anim

3. actually, no, if the olive guy had punched him it would have made sense for him to fall like that but with the force of a gun at that short of a range he definitely would have flown back, youre underestimating the power of a gun, now if that was a paintball gun that fall would make sense XD

Idk Pajama...
The gun was a sniper rifle and they are darn tough guns. I think a shotgun would do that, but i think that a sniper rifle could do that too cause a direct shot in the head would blow the person back because the head is pact with bones and brain so there is a lot of resistance but if he was shot in the stomach I doubt it would do anything :P

Anyway, That doesn't matter that much cause its the animation that we should be concentrating on. I haven't seen your anims in a while but this is pretty good.

I'm going to just elaborate on Pajama's great CC a bit :D
You main problem here is your choppiness as with many of the people on this form >.<

Try to make sure that you do not put the object in an awkward spot. For instance with the blood. it goes all over the place near the end and the arm of the shooter moves when the gun doesn't move >.>

I suggest doing this. I just found this out. If you have a PC there should be a magnifier application. You can zoom in and out with that to make sure that the grey bit (previous frame) fits where the frame before was or fits the motion you want to fit.

I agree with pajama on the gun recoil. There should be a quick ease in it. Something like this.

and then coming back should be soft.

and the last thing that I want to point out is the arm >.>
Ummm... I would have made it a tad bit different but I'm going to try to go with the technique instead. When you do something like that. Like a gravity bounce. You want to make sure that you ease with it but don't be choppy with it. When you did this the guy landed awkwardly and then waited a sec to move. In real life he would have done something immediately (if he lands some way then he stays like that). If you want the stick to be flat when he dies make sure to ease that stuff in without choppiness.

I can't really expand anymore... Well... I could... But it would take a really, really long time. :D

hope I helped

youre so good at cc pivotnoob :)
