Needs much improvment.

A tip of the hair is missing on the left side of his head. His little finger isn't attached to the rest of his hand on the right closest to the bat. The lines aren't smooth and noticeably choppy. Maybe use a little more detail. All of these faults are fully present as soon as you see it in full size. Maybe it's not such a good idea to zoom up.

Hmmmmmmmm

I like it
