Need critiques for my fire render.

Hello blender users, I am somewhat of an intermediate user looking for ideas on how to improve my fire render which I am not yet happy with. I am mainly interested in how to improve the overall flame look or what settings I can add/change rather than the composition of the image as this is really just a test.

Sorry about the low samples and the fact that the website converts the transparent background to black resulting in a somewhat ugly border between black and fire. That is normally not there.

Fire seems good. The only thing i want to know is that why the particles are looking too sharp or harsh.

I love this image. But the smoke looks too tight and not like a smoke would look in real life. Give it some blur and see how it works.
