I'm a member of quite a few Facebook groups for showing off or advertising comic art and sketch cards. That's where I discover a lot of the artists whose art winds up in my collection. Earlier this year, I bumped into artist Bun Leung's work and started following his Facebook page. That also let me to his online shop, where he's got a variety of comic and pop culture art for sale. He's even got a section of affordable art with full-size sketches under $10 in many cases.
I picked up a She-Hulk sketch from his store, but I don't think that one ever made it onto my scanner before I put it away. Then I saw a post from him on Facebook advertising a limited number of sketches available for commission. I was able to get on the list, and I asked for a sketch of Power Girl for my collection. It didn't take very long at all before he sent me a picture of the artwork and shipped it out. I'm very happy with this sketch. If you're looking for affordable work in an anime-inspired style, I'd recommend giving his shop a look or following his page and looking for commission spots to open up.
