I did some animation on fire for Hotel Transylvania the game. I personally think you can add a few frames when the fire is in the squash position. That way you can create a feeling of anticipation, and that way you can get contrast to your timing. The timing is a little even right now, think In tempo and your animation will have rhythm.
Thank you very much for the suggestion! I should have removed the Critique requested sign since I don't have any intention to revamp it. But I will keep your suggestion in mind when I am going to create a new fire animation.
and I have a question: can I use this for my avatar icon?
of course
