MYER Fashion show, 27th Feb. First pics

Hi all,
Thanks to Wendell, I got an opportunity to shoot MYER fashion show which took place in Melbourne yesterday. This was my first attempt at fashion photography and I'm not quite sure how badly I went. So any critique or suggestions are greatly appreciated. I used Nikkor 80-200mm f4.5-5.6 which is not the best lens, but that's all I have at the moment, in that range. I had to use ISO 640-800 which gave significant amount of noise in some images. The lens' sharpness is not best either. I really need to upgrade to Nikkor 80-200 f2.8 insteadThe other problem I had is sometimes I wanted a wider focal length, but that would require changing lens which I did not have time to do. 80 mm was too long in many cases, and I could not capture models in full length. May be I should have used my 50 mm instead.
First, a social pic taken at the arrival. Unfortunately (or fortunately) I am completely ignorant in anything to do with sports and whilst I know he is a swimer, can anyone give me his name? Pity his girlfriend/ partner is not looking at the camera. This was taken with Nikkor 50 mm f 1.4
The rest are from the show:
Again, any C&C are more than welcome.
Thanks
Alex
