lol, I like to use K' but when I try I use to lose as well xD

The piccie is very interesting, the fact you used only red and yellow thones make it pretty atractive to the look. The pose is pretty nice, it reminds me a bit to Kyo with the orochinagi.
I love the way you cged the Wrinkles. they have not lines at all, and you use the shadows to show them. is something i want to learn someday >w<

the background looks very rushed, still I think is proper in this case because we are looking through the flame, and that makes harder to see it (because the hot air movement first and the smoke if the flames live for some time)

anyway, I think maybe you put more effort drawing the face and the hair that the rest of the body (at least the lines from the head are more visible than the ones from the body, at least from the clothes, but maybe you wanted to do it this way, maybe to show movement or the hot air?)
