Solid Snake Sprite

[Hoeloe]

Looks pretty stiff, and the colours aren't wonderful (some very low contrast in the skintones, for example), plus it's very cluttered and hard to read. For a sprite that size, try not to put in all the detail you have. When working at low resolution, readability is key. That is, forsake details such that you can see what's going on better. Also he has a really tall head.
