Hmmm..

To take the thrill out at first:
Excellent idea, excellent composition, excellent colours, excellent expression and handpose.
I would consider this an excellent shot!

What I like at your image is the use of the belt (?) with it's really, really strong colours (which would normally make me run away) together with the blackish mood of the rest of the image. The "V" of thumb/index gives a resting point to those colours, so I forgive you that you used them.
( -just kidding, they belong there!)

The pressure of the fishnet-thingie to the skin and especially to the lips gives an additional and somewhat disturbing (which means: GOOD) information layer, and you expression is priceless, as usual.

I would have left the straps of the tank-top out, or would have used something (black) that covers the visible parts of the collar/shoulder.
Hard to decide, which of the solutions would have turned out better.
I tried to cover the spots in question up with my thumbs, but they look stupid, there.

From the technical point of view the shot is above all critique - the light is clean, the lights and shadows are in tghe range they belong to, and the thing is crips and clear.

There you have it, Ladies and Gentlemen: This is art-academy-application-portfolio-stuff, but I guess you know that.

Bravo. Bravo!
