I posted three designs for critiques. So far everyone has been very helpful in guiding me as I brainstorm on future improvements.

I'd like to do more with photoshop. I'm more used to Illustrator. Does anyone know of a filter in either program that will give me the look of old comics blown up? That retro-dotty look? I have a few ideas and wanted to experiment with that. I've tried all the filters I could find in photoshop but to no avail. Alas.
Help please?
