Thanks to all who bought one. This is inspired, obviously, by the Ray Bradbury story A Sound of Thunder.
Not the greatest I could do but it started as just a tyrannosaur sketch and evolved into what you see. If I had set out to draw something from that story I would probably have picked a low angle looking up with the hunter at the looming monster. Maybe that's why nobody bought it... HA! Will post other con sketches later!
