You looked GREAT!... and to place so highly with so many competitors is also tremendous.
Your physique looks very feminine. Nice tiny waste, good lower and upper body development. Your upper body seemed a tad bit unbalanced with your lower though from what I saw your legs had better development. It would seem that you would benefit from a *tad* more on the top to match the bottom. You have a good skeletal structure so I think that you would do well competitively and your posing was awesome...
You had the red bikini for evening?
GREAT CHOICE.
Excellent effort on your part, you should be very proud!
