great stuff guys
elGerman - it doesn't have to be a human, no. As long as one can tell that it is a marksman that you're looking at and not a random creature
Crazy3D - good progress - you could revisit the overall proportions of your character. Also don't go too much into detailing the face without getting the structure of it right. I'd especially suggest looking at how the lips are constructed - remember that the upper lid always lies on top the lower one...
Keep going everyone. Also - if you could please embed your images in the post instead of using attachements. It's hard to look at your work otherwise. [use an image hosting website like Image Shack + the insert image button in the form of a picture]
