If you want to do fire right you need to take a long time with it.
Here's Boric again. I think I'll keep the chest fire, but not the blue markings on the back.
Your line art is great Spotty, but I think it still looks a bit too feminine. Thanks for making it.
Edit:
Forgot to put in the highlight when I was done. Fire is much easier when you don't have all those shadows and highlights lurking about.
