Hillgrove's site is titled "Imps and Monsters" and for good reason. It's filled creatures of all shapes and sizes and colors; there are a few people and robots but it's clear that Hillgrove's passion (and talent) lies in the weirdly tentacled, horned, clawed, and furred.
It's not just the monsters themselves that stand out, though. Backgrounds are beautifully done, and the colors on each and every image are superb. If you're looking for something a little more familiar, Hillgrove also has a tributes and parodies featuring zombie Peanuts, "the usual suspects" including Jack the Ripper and Sweeney Todd, and an excellent piece based on To Kill a Mockingbird.
It's encouraging to see so much originality in one's work. "Imps and Monsters" has a ton of work for sale so go show your support and purchase a few pieces. You can also pledge to Feeble's Fable to be able to see his work in glorious 3D. There's a lot to appreciate here, and only more to look forward to in the future.
