Getting there

Samuel L Jackson [WIP]

This is what I've been working on the last couple days. This is my fifth attempt, I think. I haven't been saving the ones I didn't like.
Still working on it. I don't think it looks much like him at this stage. What do you guys think?
Critique, if it pleases you.
