Cool. I hope he does.
He's a well known name in creature/figure modeling & painting, and you don't get to work on movie projects like what's in his portfolio without being reliable. But at the same time, something I've seen many times in the small hobby biz is folks who are otherwise perfectly stand-up individuals starting a sideline shop in their spare time, then ruining it by mentally miscategorizing transactions and CS in the "favors" bin instead of the "professional obligations" bin.
Not saying I'm already assuming that, but the business about going through FB is a wee red flag, TBH. It's fine if FB is the best way to contact him, but if that's actually the case, there should be a link to that on the "contact us" page instead of a form to an email he doesn't or can't check regularly. I now kinda want to know more about things like shipping time frames, shipping notifications, order confirmation, and probability of response to status inquiries in the event of prolonged absence of any of those before I commit money to an order.
