Very good ... your concept is very sound and your choice of stock is great; you definitely have an eye for composition. There is a little more work needed on the cutting out of "Pandora".

If you are using a program with layer masks try using them to mask your image. You can start with the lasso tool (or whatever tool for selecting you like) after the basic selection is done you can go in and really refine it with a brush, I will even use the smudge tool to smooth and soften the outline.

Layer masks and adjustment layers give a lot more control and are non-destructive so you always have you original to go back to for reference. For fine tuning nothing works like a layer mask/adjustment layer

NOTE: using the Pen tool is also a great way to create selections but the learning curve is a bit fierce, worth the effort though!

thanx a lot frnd..did some changes...hope its ok now

Much better ... again nice choices! GL
