After going through several (very different) iterations, I ended up with the image below. I've always liked the iconography of Pink Floyd's "Dark Side of the Moon" album cover, and I was really happy to work with it. I put this into a cover template that I re-created in Adobe Illustrator of the journal Neuron.

I started the piece by painting it in oil paint on a 22"x28" canvas board. Then I photographed that in with a high-resolution digital SLR and digitally airbrushed it a bunch until I got it close to how I wanted it to look. What's uploaded above is not my final version, but I really wanted to upload something new, so I'll just replace it with the next version after I have gone through my critique and modify it.
