Before I get down to business, I'll just introduce myself quick.
My name is Robert, I'm 16 years old, and have been drawing for a little less than two years.
I've been looking at a couple of conceptart sketchbooks for a while now and decided to jump in. Improving is so important to me as an artist, so what I'm looking for by being active on this forum is some solid critique on anything and everything.
Anatomy and value in specific are some of the main areas I would like to improve.
That being said, here's some very recent stuff:
