Okay, all of these commissions kind of have a specific formula. Each one has parameters to fit into, but they're a fun choice if you don't want to spend quite as much money on a full background piece.

All of them, except for the Stylized Character Portraits on Coordinating Paper are done on 9" x 12" paper with at least a 1/2 inch margin around the image to make it easier for matting and framing purposes so that little if any of the image is lost.

Keep an eye on my journals for specials on these. Usually, these are really fun to do and are completed quicker than most of my other commissions, so I'll probably run deals on them from time to time.
