These are great. I think I stumbled upon the game's site a while ago. Looks cool.
The only crit I have is that, in addition to what Kevin said about the gun's angle, the firecone also looks odd since its center is never completely bright. It seems to have a dark pixel there, which looks really wierd.
Is the kneeling animation supposed to be divided into 4 parts? ie. standing, kneeling, kneeling lower, and kneeling low with "!"
If not, it looks wierd 'cause he kinda goes down, then jerks for a sec, then goes down some more.
