I suck at drawing but you have some skills here. Just keep grinding it man and get the depth of the character embroidered in the drawing and youll be at 5 stars in no time. Just convince your viewers hes a demon...make something sorta off about his appearance thats makes people say "Yea, this dude is screwed up". If you put emphasis on it im sure 5 stars are all yours my man...great work.
