The helmet looks more like a skull head then a skull head wear. If you could finish the legs and not make them vanish then that would be good too. Overall, you got another five from me. Good job.
5/5

his right arm looks a little smaller than the rest of him, but other than that and what BR said, it looks Frikkin awesome!!!

That is SO cool!!!!

Thats a really nice drawing the only thing i dont like are his hands. I know hands are really hard to do but they just look too small.

your shading skills are great it would be nice to see what you can do with color

Looks great, except, as others have said, the right arm is out of proportion, and the hands are too small. A few other criticisms: the "horns" on the mask seem like they should be bigger and more prominent; the lower left part of the chest strap (that is, the part going under his left arm) seems too high up compared to the right side; and the spear seems too small. Other than that, excellent shading, mostly excellent anatomy, and an overall great depiction of a great character. 4.5/5

damn- that might be an old post but this is one of the FEW times I am glad someone bumped an old one. This looks FACKING awesome! Only minor issue is artist forgot to shade Khans lower jaw area under the mask.

Very Nice its like you made a Badass well... more badass!
5/5.
