Simply lovely! I particularly like his, what do you say, posture? That subtle subtext of attitude from his pose, from the look in his eyes - it says he is above finery, and that flame-spitting beasts are for him like kittens to be petted absent-mindedly. Splendid!
I do not know if it captures his appearance (I imagined him as being a bit less handsome and more aged), but it depicts his character (as, well, a character) so very well. I love your artwork, keep at it!
