The line work displays the character well, but it looks flat. Try using different line thickness to improve that. Shadings alright could be better though

hey dude! Love this picture, picos face was spot on, lines could be a bit thicker, maybe a little neater shading? but besides that great picture and get on skype

Boss. I like the colors and the line work. I don't think you should clean it up at all. A question if you will. What art program do you use, do u use after effect? And do u hand color it?
