Interesting. I might try a few alien worlds later, when I can tear myself away from the cats and other magical critters. The Star Wars and Star Trek universes alone ought to have fascinating architecture, etc. Not to mention all those metal bikini-clad alien chics. Nowadays I mostly do fan art, or what used to be fan art but is now not since the source has gone public domain, like Sherlock Holmes. Barring that, it's flora and fauna, or some non-fannish stuff I probably could sell if only I could be arsed but I'm retired, disabled and trying to stay sane in a crazy, crazy world. So it's fun, and (hopefully) cheaper than therapy. ;-)
