I dont honestly like the face at all, some of the parts on the suitarent in proportion to where they should coencide with his body, and the line work is shotty at best.
Dont understand why you used any lead based medium for a piece you were going to color.
Because of that you now have those unsightly white patches in the picture, and worse, those ugly looking gray smudges and lines in places they obviously shouldnt be.
Overall, its decent work though, and besides the flaws it has that keep me from truly liking the art, the coloring is well done and its above average at least.
Keep doing what youre doing dude.
