Things I did here:
-hue-shifted shadows, to add a bit of red to where the fire lights up the scalp
-consistant shadows across all parts, notably the shirt and hair
-added "bright flashes" for when the fire got bigger, making it seem more intense and bright
Things I didn't do:
-try very hard to keep said shadows consistent
-add any shading to the arms or face
-realize he had a ponytail and thats what the whippy bit was
