AThis is messy as hell. Armor looks like scribbly crap, and the leather shit on the arms is bland.
Also, im surprised nobody noticed, but the shading on the armor is incorrect. Its casting shadows upward...
FOr a first skin, im still gonna say bleh. No, its no disgusting, but its not good. Btw, blood on a blade is stupid, rarely ever should someone use that.
Heres some tips:
-Clean your work up, use a blending tool.
-Color your character correctly. Orange, grey, green and Team color dont mix.
IF this is all free hand like you say, this isnt so bad. You have potential, so try an idea of yours on your own.
