Aside from that expertly done chainmail, the crazy pyrotechnic magic he's conjuring in his hand is very nicely done, love the look of it. Really digging his hair too! And...did I ever mention how much I love the intricate, decorative bits you put into the armor and clothing? Those spiffy little embellishments add so very much to the overall look of the character and really make them standout.
On this one I love how the flames of the sword seem to almost create the wings of smoke and shadow.
I also like the tiny details like symbols at the bottom hem of his robe, or how the colors work to compliment each other. the red at the bottom of the robe blending into black, and the black of the wings blending into the red of the flame, etc.
