A couple things: learn to light your photos, as that'll kill you in a heart beat when they're looking at thousands of artists a day. Get rid of the quotes, everyone in art school reads as much as you and it is cringe inducing to see those quotes placed like that. If you really feel they need to be there, figure out a stronger way to incorporate them. Those drawings should be taking about 5 minutes a piece, so there should be a thousand of them on your website. The more the merrier, just create a separate section for them and post all of them forever (except the truly awful ones).
Also about the quotes, maybe those are just for your tumblr and if so that is fine, just don't post them with your work.
