My name is Harrison, a geeky, queer artist currently based in Portland, OR – and the face behind Fiendish Thingy Art.

As an illustrator, my passion is for creatures and monsters both of this world and from my imagination. I love world building and concept art. I create art that balances creepy, cute and  mythical, and also some based on popular culture – basically, fandom and geeky content. Currently, you can find me here on the web – when the current Pandemic subsides I hope to get back to conventions across the country!


I update my social media most often, so please visit those sites for recent art, doodles, and day-to-day nonsense. This site is mostly a place to collect everything in one spot, with my store, galleries, appearances, and links to my social media accounts.

Also, please, if you love my work, consider supporting me on Patreon. You’ll get access to larger works-in-progress, voting on name suggestions for new pieces and projects, and you’ll have first access to new art.


I trained in Illustration and Visual Development, and have been creating art as a freelance artist for over 15 years. My preferred tools are watercolor and ink. My areas of focus are concept art (particularly creature and character design), narrative illustration, caricature, comic pencils and inks, pet portraits, and visual development.

Take a look around, I hope you enjoy what you see!
