Most of my alien menagerie project exists as piles of pencil sketches. The time I have to work on oil paintings is less than I'd like, so they take quite a long time to complete. "Extracts" is the name I've given to a series of more casual paintings that I can complete with more speed and spontaneity.
The aliens in these pieces are pulled straight from my sketchbooks. I'm not worried about setting up an environment for these, or how they might fit into a more elaborate piece or series someday. I like to think of them as plates from a journal or guidebook of various 宇宙人。
They're acrylics on Rives BFK paper (7.5x10"). It was really fun to pick up acrylics again for these pieces. I used them for most of my career as an illustrator. There's a comfort of familiarity that I haven't acquired for oils just yet.
