So, I've raised the price for these whiteback sketches this past weekend, with the re-jiggered shopping cart, from $10 to $15 per card. I'm afraid that by doing so I'll simply be giving myself more permission to spend even more time on them, and I'm aware that there's a ceiling for pricing on these small drawings. I'm not sure where, and I don't want to hit it.
Drawings that span multiple cards can be rendered in almost any configuration and orientation. Here is a 1x2 drawing based on Soul Warden:

I also have done some World of Warcraft card sketches:
