I thought the beast has the body and neck of a herbivore, but the head of a carnivore. The front of his saddle will impale him if he's thrown forward. He's left handed (well that can happen of course) and his weapon is far too small to be of use while mounted. His breast plate goes out too far on his shoulders reducing his ability to reach across his body, and too far down his abdomen reducing how far he can bend (Although there were some breast plates with this feature in ancient and more modern times. For example, Napoleon's unhorsed cuirassiers were said to roll on the ground like upturned turtles, having to get on their hands and knees to get back up.)
How did the very nicely painted girl get there? ( I suppose she could have hung on the back for dear life.) What bothered me most though was the way the open dragon maul was being ignored. No effort at all to control, subdue or acknowledge the cause.
We'll see if I make a fool of myself with my picture.
