Experimented a bit with Materials, HDRI maps and Volumetric effects.
Result:

not cool... try better

Infracted: Useless post, constructive criticism. ~Blam

woah trippy!

its a bit too stylized tho.

i dont know about rendering but i say that looks epic O_o

neet. tis a bit dark though

Well, the ice looks the wrong color, but the fire is great. Where does volumetrics come in?

Yeh the ice did turn out to "soft" and with the background the colour is a bit messed up.
The volumetric ligt: Look at the halo arround the fireball.
The fireball got a transparency layer and a volumetric light in the inside, so that the firecracks are glowing more realistic.
I wanted to try if I can get good results with volumetric light passing through transparencys or if it even works, well it did work better than expected :P

pretty cool
not your best work though.

as has been stated, not your best work.

I really don't know what to say, I have no idea how you made it, when I first looked at it though I was like "why the hell is nightmare filter-spamming in photoshop?!?"

sorry :P

still looks ok though.

Unlike everyone else here, i reckon the ice looks pro. The fire is pretty cool, but the ice is the best. Reminds me of final fantasy style ice. Good job.
