I am a fantasy nerd, and mythology buff. When it comes to dragons, that is my home turf. I really am thoroughly impressed by the detail you have gone through with this picture. It truely is magnificent. If I was not the poor college student that I am, I would totally buy this from you (or commission you to make another) so I could frame it and place it in my future study.
What really got me (besides the tails) was the runic markings across their bodies. That was and is a very nice touch. I look forward to seeing what else you will do.
