keep it up, i can see improvement already. good to see you starting to understand "bounced lighting/reflected lighting".
and dude, if you have something to add to what you've said and no one has replied in between, you can always "edit" your last post, and add whatever new thing you need to say at the end of your previous post. there's no prize for having lots of posts, and having lots of empty posts in your sketchbook. it'll make your sketchthread cleaner and more grown-up-like.
happy belated birthday.
