Robot Print

I drew a robot drawing in class one day when the kids were doing something low maintenance that didn't require me walking around every five minutes...we were looking at old Ed Emberley books and that's where I got this cute little robot from. (Believe it or not, but I never had any of his books until this year when the Media Specialist cleaned out some old books and now I have two--the Big Orange Drawing Book and the Big Purple Drawing Book. I am now addicted and want ALL of his books!!) I played around with my drawing in Photoshop and this is what I got:

This one has a film-grain texture on it and a darker contrast. You have to click on them to see the texture better.

This one has a brighter contrast with a texture applied.

I can't figure out which one is better.
