It looks rather like "inflight" but with the eye makeup changed and the reflections on the lower lip gone.
OK if i'm looking for reasons not to choose it as a comp winner - and i'm being over picky here as you work is one of those i aspire too.
The reflection on the top lip is very dominant and almost square, her left eye (as we view it here) is black but the other is blue.
maybe light pink nail polish similiar to her lips would add impact? the light on her left forarm seems to transition from white to grey with quite a hard line - could the grey be lightened just a tad? this may also help keep her arm seperate from the background on that side.
Some other crazy ideas - could the hair be made more blond to match the dress - more like that odd blond curl on top of her head?
Could you clone in more mesh over her left arm to make it seem joined to the dress, the hair is so dominant - could it be blurred just a tad on the far LHS to lessen its impact?
Feel free to ignore all the above as i'm still quite amatuer and have no ide what judges may like.
Best wishes anyway,
