Nice emote. The detail on the wing looks great and the fire effect is pretty good. You've also managed to make the animation really smooth, so overall it's not bad.
I would however suggest that you move the wings closer to the emote's body. I like a couple of other people originally mistook it for a tail because of it's position on the body and the line of pixels between the body's edge and wings main area. Either that or change the colours to something like a white/cream.
I'd also suggest removing the white pixels found around the edge of the body. Whilst it looks fine on this colour background, if someone was to use it in a journal against a dark background colour then the quality of the piece decreases as they stand out a lot more.
Even if you choose not to do it on this emote, it's just something to consider for the future or if you make a revamp
