Cartoon fireball VFX

Hello, guys! I’m quite new in the vfx area and this vfx is a bit experimental. I tried to achieve cartoonish fire look. Inspiring by Spellbreak (https://www.artstation.com/artwork/OmqdKg). I am not sure how good is my fire. Also I wonder if the smoke behaviour is correct. I tried to implement correct vfx fundamentals, but maybe You saw something what I can improve? Thanks for any feedback!
