Walt from Breaking Bad WIP2

I'm actually currently done with his face structure (lacking details still) and finished his mustache and starting on his beard. Sadly my camera broke so this is the latest picture I have of it. This is the last decent picture the camera took, but even in this you can see random line, and this picture actually came out fully purple for some reason, I fixed it with an image editor.

I plan on finishing the drawing in the next couple days.
