Jeez, your lighting effects are amazing!
I'm still new at digital stuff and I kinda use a similar technique with the blurring but I've had to substitute decreasing opacity for the lighting stuff because I haven't figured out how to work the lights in GIMP yet. That was very frustrating for me in mine. I did the same pairing as you and it's really cool to see such a different take on it. My orc is a skinny reject which is why he turned to wizardry and he's summoning the demon from the center of a hedge maze (not a labyrinth) in order to try to make a deal, setting himself on fire in the process. (And summoning a sharknado)
Yours looks absolutely professional in contrast (and in general, actually). I think you have a real shot at the win. Good luck!
