The dry hair in a pouring rain looks a bit weird...

Thanks for the feedback MossyB..good observation..made some changes to the hair.

This is some awesome work, check the rain/ water details in hi-res folks.
You could experiment a bit with the blending of that girl. I get that you wanna make her like she's transforming as shes passing through, but IMO her back side should still be desaturated and overlayed with green-ish, the colour of the environnement.
EDIT: now that i changed the screen i realize that it was not green-ish, but you get the idea, she needs some desaturation and some lower brightness on her back,hair&hands,try with some level overlay.
PS: I DON'T usually make comments behind a messed up PC screen ,..

Pure beauty...

Looks so nice.... good luck... I like the colors.

Thanks for the comments..at greymval, i had tried removing the blues and cyans from the dress, but when i did that it made the dress too desaturated and it removed any depth that the model has with the stone structure and it felt too flat..so i left it with that little bit of blue..thanks for the comment tho, good suggestion

I like this, the only thing I might have done differently is the color of the forest she is walking in to. It looks too red and it makes me think of fire.

very very good work author...love the model...best of luck
