I've found a few things already - pictures of coins, St. George and the Dragon, and so forth - but not nearly as much as I'd like, and most of what I've found on line shows dragons fighting. I need a broader range of subjects.
I may have a go at making some models and photographing them - I can't use commercial figures since they will be copyright. Annoyingly I used to have a couple of fairly large dragon models I scratch-built in my D&D days, but they seem to have gone missing at some point in the last ten years or so. Other than that, any suggestions would be greatly appreciated.
Later: I've found some free sources on line, and with a little manip ended up with this:
Since he's a bishop he should have his wings tied, still trying to work out where the cords should go. I also need to do something about the colour, it's wrong for a male.
