Blackmage

Alright, here's a bit of a critique. The pose, anatomy and that kind of stuff seem quite alright, so nothing to worry about there. I do reckon, however, that your use of values is a tad off. Don't really understand why you put blacks in your fire. Fire's supposed to be a light source, whereas black is known for its complete absence of light. I hope you understand this is a bit ...odd? Other than that, use brighter, more saturated colors in the fire. Except for the bright yellow's and oranges in the fire, the reds seem rather desaturated and dull, especially compared to the purples of the character's coat. Finally, not too big a fan of the fire brushwork. It seems you used a bit of a textured brush there, which can be alright. But, in this case, and especially near the character's feet, it feels a bit off. This is probably because it contrasts too much with the smooth brushstrokes used on the character. Finally, don't lower the opacity too much, makes your strokes, especially the black ones, appear to be a bit muddy.

There you go, my critique to you
Have a swell day.
