Clever idea, but work with the details. Her left hand fingers are cut off and the masking below the hem (upper legs) has a problem too. Also the outline of the dress (especially right side) is a bit odd. You could try warp tool to manipulate it a little bit more. Clean the edges and your masks and give the pale woman some colour on her skin. The dress'es lower part could be a bit more thinner and just a little bit longer.. now she looks a bit fat

Very good idea, work some more with it and you can make a good one.

I agree with Widiar...

txs for ur advice. the dress i created same as original image and the some part of fingers are inside the dress. but i know i am little bit lazy.

Art is not for a lazy person they say. You can try to find some nice flower or other ornament to hide the missing fingers if you can't fix them. She's holding some strange decorative stuff anyways, so it would fit the theme.

ok........ i can understand.... i am a beginner in photo shop.i got little time for work with photo shop. i dont know much about ps and need your advice.thank you
