I commissioned an artist months ago for a design commission. At first they were quick to respond to my e mails with WIPs, but now they don't seem to remain in contact. I had to e mail them for status updates every few weeks (they had to go somewhere for a few days, but I didn't know). And it's still been several weeks since any contact. This leads me to believe that they don't want to work on the commission anymore. I understand what it's like to lose interest in a subject, the issue is that I already paid them months ago and haven't gotten a solid product. I wouldn't mind it taking this long, but they haven't sent an update at all.
I have no intentions on getting a full refund, because they already sent me WIPs. My question would be if it is alright to ask to change my commission to something else? The difference of the refund would just go towards another type of commission?
I think the ref might be too daunting, and maybe a sketch would be better for the both of us.
Thank you for your time!
