Really amazing work. I have to say that I lean toward your personal work but it's all good. Your self-portrait is great and I'm really impressed with what you can do with Illustrator, I know it's great for printing but when i was using it it seemed kind of limiting, photshop seemed more close to what I understood with traditional art. You make me want to look at it again.
I missed the first that you were doing the ones before with your left hand, I think that's a great exercise, I spent a year and a half doing that when I was studying with a teacher of mine, it really slows you down and makes you really look at what your drawing and after a while you don't even notice that your drawing with your opposite hand anymore. He used to say that your dominate hand has an ego, it thinks it know what it's drawing without really looking. It totally changed my drawing style for the better.
Keep them coming.

Huge and very interesing update. What a treat! You are a generous fellow. Very professional work for websites, I think. And you self-portrait, I like it a lot. Very, very truthful expression of the face. These eyes. Looking right at me. Great, great work
p.s. I see you're trying a new manner to draw, very different. Keep it up.
