well.. the drawing is a little simplistic, but that isn't what turned me off.
what turned me off was the lack of wit and humor. i think it's trying to be funny, but the way the dialog is written, and the way some of the text looks like it was just typed in without a care for presentation takes away from that. if you can fix that, then you have charm. good looks are still to be desired, but everyone knows that personality goes a long way.
