It's fine, it's a more general question about map pack structures.

I create my maps at the required final print size. Usually it's single page letter - 8.5 by 11 - at 300dpi. In this case it's 11 by 17. I've done higher resolution a couple of times, but there's really little need and it ends up taking more time in the end, for little gain.

I now illustrate almost exclusively in Photoshop, though I mean to get better at Illustrator.
