some advice
Personally, I suck at computer art. The sound sucked, im sorry, it did. I think you may be good at drawing on paper, and I like the gradients, for christmas ask for a wacom art pad (I think you are drawing with a mouse), keep practicing. Also try watching alot more tv, not to steal jokes but to get an idea of rhetoric and situational comedy a good example is the three stooges, family guy and of course the simpsons.
