Very good indeed, but there are some minor changes that are needed:
-His hair:
You have it thin, and almost like a pineapple. It's more spread out, and bushy. Try to make it random, or even add some small curls to the end of tips, (Make waayyy more tips btw)
-His eyes
That shape (and proportion) is wrong, they shouldn't look like that. They're took close together, so I suggest making them smaller. there should be a gap of one eye's length inbetween them.
Still, I love the messiness, and the fab colouring of this piece! Keep up the excellent work ^.^
