I would like to commission something other than drawings as well. I've looked into photosets from people, but I did one with someone as a test and it was horrible. I won't mention anyone specific, but they claimed I never paid them for one, even when I went so far as to show them the very same e-mail address that they gave me they went on to say "that's not the right address, it's [exact same address]." Not only that, but what I got was neither what was advertised nor what I asked for. I've had some less-than-good experiences with commissioning before, but I won't hesitate to say this was the worst. Still, even with that souring experience I'd be open to trying an actual photoset again. Not with them, of course, never. But with someone else.
A while back, too, I was set to commission someone for pixel art as well. Everything was set up, but nothing ever came of it so I'm not upset about it, but I'd still like to get a pixel art commission sometime too from someone that doesn't just use one of those base things.
Just some general thoughts. As always, feel free to chime in
