Ethan Van Sciver and I talked through private message last night and we're able to work through the issues that I had. I can honestly say that Ethan and his wife are wonderful people to deal with at conventions. I think that his commissions may have gotten away from him but the end results are always worth it.
In the end better communication on both our parts could have made things a lot easier. I know I've definitely learned from this experience and will use this knowledge when setting up future commissions.
I'm hoping that Ethan doesn't stop doing commissions. That was not my hope or intent. I think it would be a disservice to his fans and to himself.
