The orange is definitely an improvement to the fire, but I think it could be adjusted even further so that it transitions much more smoothly with the red -maybe let the orange be your transition, and expand the lightest color of the thrust to be your only highlight.
I'm also counting a lot of extra blues in there that are awfully close to one another -- the number of colors you use is your call, but if you want to reduce your palette, you can always mix-and-match some of those blues.
