Okay, I used "TinEye" to reverse-image search, and I believe this work comes from Star Wars Visions from 2010. I'm going to see about borrowing the book to check out the other art; will let you know if I find anything interesting.
Btw, in my search, I randomly discovered this interesting collection of art tips from the master. As an artist myself, I feel like there's a lot for me to learn there, wow!
