Twin Peaks Portraits

I've really wanted to improve my ability to capture likeness and just generally improve my observational skills. So I have been doing some value studies based on the characters of Twin Peaks. I tweeted these at the actors and a lot of them liked them. So that makes me feel like I'm starting to get this down. This will be updated as I make more. I seem to need to do two portraits before I nail it down. The first one gets me in the realm of their likeness while the second one I hone in it more. It's cool to see the improvement.
