Battle of the Kings

Do I need to put a Mature Content filter on this?

Illustration of a scene from The Dragon Wars (Chapter 14). I've actually had the sketch for this stash away for a few months. I decided to finish this picture now since the part of the story it depicts is available now. I would've gone all out on the blood in this illustration, but I decided against it.

Tregondor and Tregoneron fought ruthlessly. They flew around each other, clawed at each other, and shot fire at each other. At one point Tregoneron slashed at Tregondor’s chest, leaving an open cut. Tregondor attacked back, biting Tregoneron at the neck. Then he slashed at Tregoneron’s left wing, creating a hole in it.
