That works better! Hope you finish on time!

Decided to mix the dark and blue backgrounds! Not sure about the colour of her hair at the moment, haha. C&C always welcome!!

Your best bit of fire in my opinion is bottom left. The fire on the sword needs a softer brush to blend all those brushstrokes together. Remember also that fire is hottest at the bottom, so changes colour as it moves up. (The sword flame is yellow all the way up at the moment.)
I treat fire a little like fabric that's blowing in the wind.

Yeah you only need to make the fire more consistent with the same colors. Now the fires are different, and I don't think that is what you want?

Update - Colour of the fire, added details to the horns. Would love to know if there is anything jarring that stands out that I should correct, I've been staring at this piece for a long time!! Hahaha!

Congrats on finishing! Looks like it really came together. Good luck!
