Noflow And the green and red dun mix. Maybe it would look better if the BG was a different color. Maybe even the same color as the guy.
green and red are complimentary colors. many famous artists use complimentary colors to make things look nice. a sig also doesn't have to be based on flow either. its a guideline not a rule. and personally i think it still looks good so that doesn't matter. anyways.. the sig looks really good, my only problem in that its pretty bare. the colors are fantastic though.
