I'm working on better backgrounds. I've been just throwing them together digitally and I haven't really been happy with the results. For this, I sketched a random background separately, inked it, scanned it, and then colored it in Photoshop. I did two, but the first one didn't fit. The environment was too small. What I will probably do for the next one is take the line art, convert it to a light blue, print that, and sketch the background directly on that.
