I like the colors & your BG, you should however indicate the filter used to make those feather-like shapes.
There are a few problems with the masking, that black foreground that doesn't look to appealing( I'm sure that light-clouds would do better) - proportions need some adjustments, since she looks like having huge deltoids and neck muscles.
The clavicles & a thin neck are indicators of feminine, not just the cleavage .

Her left shoulder (RH side) is jammed up beneath her neck.

Tutorial you could use, thx to hereisanoop.

very Classic enhancement and fix, good luck Author (Nice background shift..though I do miss the castle thingy in the back ground, but that's just because I looked at your SBS up and down several times

beautiful image

image looks faded; it needs more brightness and contrast

thanks for you comments. i fixed it. it was too light because i've set the brightness of my screen too low and it looked good for me, but when i saw it from another computer i realised it needed to be fixed.

nice fix

good

very nice. good change

Gorgeous Image. Nice work

nice and warm, try to fix the edges on the elbow

great

i think the edges of her hair a too bright

the original bg could stay imo ) nice work!

nice entry, if you give little more brightness, will be good

looks nice agree with gopankarichal

Nice image, colors & composition I would have kept the background source in its original state would have loved to see these over that water & get some reflections in there….. but that personal preference…..

they really look like floating gemstones..very cool effect... me likey

EDIT: After looking at this picture several times.. I know what this reminds me of.. it's the Powers of HAVOC from the marvel comic books..he use to throw those circular hoops off his body.. I think he was a ancient Egyptian power god descendant or something.. couldn't get it out of my mind LOL

lol that is c o o l

Where's the WILD HAIR.. the Bizarre Back Ground.. the FANGS... Just kidding..your subtle approach is very effective and well done, not as dramatic as some of the other piece's but just as powerful..if this was a wedding client you would be getting A HUGE tip for sure...hehehe.. awesome work

(Check your source link, it isn't working for me.. and I DO NOT WANT THIS ENTRY pulled on a technicality)

nice job

nice work, can avoid the blurness

simple......pretty good

Try to add a long hair, she'll look more attractive

very subtle but clear improvement

I liked the thinner version better... the perfection is somewhere in between! )) gl author

nice

the eyes are too green for me, but pretty nice use of liquify tool, still looks natural
