hey man. I think it's totally cool that you're just 14 and not acting like a fuckup like most "artists" your age. that said, I'd really like to see some proper life studies and "realistic" drawings. I've got nothing against your style, but too often people end up getting stuck in a really played out style without being able to handle the basics.
I realize I'm posting right below threadwood who is, by all means, a more reliable source than I, and also happened to give you advice that is essentially the opposite of mine, but I still stand by what I'm saying. I seriously think that it will help you a lot in the long run.
whatever you decide to do, keep up the good work and hey, good luck man. :]
