Very nice, impressive =) Good Luck !

Quite interesting.. you should crop the image where the ice-man ends, so it doesn't look like a failed mask edge. And you should anyways soften some of those huge brush edges on the mask, especially on the icemans top and under his straightened leg. Cool composition.

nice work author and great choice...gl

EDIT: Softened the water around the man, and added a splash under the right leg, and some drops on the left leg. Also lightened the water a bit.
Burned (hehe burning a fire woman? wtf? lol) the woman a bit more, so it blends better... hope so...
Also crop the image as Widiar told.
@Widiar: Thx for the constructive comment!
@Erathion and @Vlado: Thx for the support! I appreciate it!

Looks good on high resolution too now - a lot better. There is still one minor problem with the mask of the firewoman's hair, right above the hairline. You should smoothen and hide that straight line and her awesome hair looks even better. (I'm sure I'm not the only one who digs her hair..)

EDIT: Made the changes to the hair. Smudged, so the line is gone.
@Widiar: Thx again for the comment!

nice
