Well done on this icon of yours :3 I really like the flames in the background.
Thing you could touch up on:
The eyes kinda blend in too much with the background (not the pupils, the "pink part" of Ravenpaw's eye) and it seems kind of like you forgot to colour it in from the background
Things I like:
Your style is very well drawn and clean. The whiskers are a bit thick, but that depends on your style. The teeth at well done, but the density on the line on the teeth is too thick
good job though
