I think the artwork in this set is 5/5, but the 3 different PDF readers I used(including acrobat) all had a hard time chugging through the various layers and options. It could be an issue with my machine, but it's a quad core/4 gig of ram/decent vid card. I exported the parts I intended to use with photoshop and went from there with no problem. That's the only issue I could find with the product though. The small amount of story included with it is a nice touch, and the individual tiles let you customize to your hearts content. The inclusion of notes section with a picture of each tile is also very handy.
