Years ago, I drew lots of portraits, mostly from Star Trek magazines. For The X-Files, I started to draw directly from a VCR freeze frame. All because I made my first sale at a Star Trek convention art show. I made $10 from that sale off of this Scully and Worf. However, I found out later that unless I knew the organizer, there was no chance to buy a more visible display area. After a few more years, I just stopped selling altogether. What's the point if no one could see it.
