Nice design :). I really like the elements of surrealism you threw in. It creates a very interesting mood...
The figure is very nice...I like how everything about her is thin and pointy and svelt.
So much symbolism here...it'd be cool to get a group of artists together, and just anylize the hell out of it. I think you'd get some really interesting feedback :)
Really, how do you come with these ideas? A dress made out of rock is such a creative idea. The rocks look great too. They looks as they have been sculpted.
