Hey just "flipped" through your sketchbook. I think you're being abit hard on yourself. Maybe you're not a prodigy but you're still pretty good and for only being 17 and having your ethic to work your ass off I think you'll be alright. Out of the digi sketches my fave was prob the portrait of the metal guy. The octopus one is really cool too, I'm going through this whole cephalopod phase myself.
