A good couple years back I ordered a commission from a well-known and respected local artist at a then-small college convention near me - two traditional pieces of original characters my ex and I designed for a visual novel we were working on. I believe we each paid $20-25 for them at the time. I also gave them the original design sketches I had of the two characters. The artist is open about them dealing with chronic illness - fibro and lupus, notably, and how some days they're physically unable to draw, so I didn't expect to have the art immediately, but I did hope I'd get it within a few months.
A few months later I emailed them to inquire about my commissions, I needed the design sketches back to reference from as well. They told me they were still getting through the commissions from the convention and that mine was next on the list. Awesome!
I never got the commissions or the original sketches. I feel like maybe I should have been more forceful but as I'm also an artist who struggles with chronic conditions that make keeping a consistent schedule difficult (albeit mine are nowhere near as debilitating) I feel like it might've been in bad form to nag about it. There's also the fact that this person is very well liked and respected among the local geek community, including several friends of mine, and I didn't want to be alienated or be accused of starting drama.
So this is still what I'm struggling with - do I create a beware and let people know that there's a potential caveat emptor attached to commissioning this artist (who does accept online commissions, so this isn't just a local thing)? Or do I let it go, and accept that shit happens?
