some of these weren't bad. i see you went with just plain disturbing on the child molester one without inconviencing yourself with putting any humor in it. that takes some commitment to the craft.
one thing you absolutely MUST stop doing is putting 'action' in the dialogue. nothing breaks up the flow of a comic more than **he takes down his zipper** in the middle of a dialogue bubble. its implied and we get it, it doesn't need to be said in dialogue.
hope this helps.
