So, failed to read the rules and clearly messed up on a couple points on the last attempt. I'm very sorry about that, and I hope nobody hates me too much already to respond to this attempt.
Here's an actual
image. This was done on a Wacom Bamboo Tablet in GIMP, and would look much worse if not for the miracle of CTRL+Z.
I'm not a terribly experienced artist. I've been using this equipment for about a year. I've done a few panels for comic concepts that never went anywhere, but this is new, and I do consider it a personal best, whatever that means. I'm particularly very proud of that dumpster back there. So, naturally, I'm throwing this in here to get humbled.
I'm interested in knowing if anything just looks ... amateurish, I guess. I'd like to know if you see anything that betrays a lack of technique knowledge, either in cartooning in general, or perhaps the use of GIMP or similar software.
From a practical standpoint, I'm a noob, and I want to know any reasons my artwork hurts your eyes.
