I went ahead a took a look at the rest of your gallery and can tell you've picked up on facial anatomy rather quickly, this piece being a perfect example of that. You're also well versed in your use of media, which is something i admire in your work. I'm always envious of those who start to understand these things before I did, but I also know that this is a good thing for the art community as a whole. So well done on being very good at what you do, and thank you for learning as quickly as you have.
Please, keep it up!
