Unfortunately I know little about the historic Greek Spartans and their actual appearance. The coloration of the skin is due to the reference picture i used. I have a feeling it was supposed to be either brass or gold painted armor.

Uhm... what?

Thanks :D

well i'm not really sure what kind of advice you are looking for. but for starters, making teen hoodie skins, mob based skins, and anything else extremely common (unless you can do it in an incredibly creative way, or have phenomenal shading) will not go over well.
I also recommend you do not use noise, something you appear to use for hair and the pants. (its more of an issue with the pants).
Beyond that, your skin reflects that you are a beginner, there are wrapping problems (especially with brightness) as well as the general unoriginality of the skin.
sorry if this seems harsh, but i'm a harsh (and experienced) critic, especially in skin technique.
