I commissioned other artists during AC [July 2 - 5], and they have their reasons for why I've yet to see progress. This leads me to the following question:
How long is too long to wait even for a premier sketch? I paid anywhere from $35 - $50+ for these commissions, and I've yet to see anything. When (if I end up having to) should I ask for a refund? I have kept my AnthroCon receipts, so I know exactly how much to get back just in case.
All artists in question are active, are in contact, have been paid, and have references.
Edit: In response to a suggestion here, I asked one of the artists if they needed my references again. They said "yes, please." So maybe that will result in something. ^_^' I guess they were a bit embarrassed.
