Cocktails always make for a better shoot! I love this shot! Very nice lighting, and a great pose with wonderful leading lines. My only critique would be composition. She's somewhat bulls-eyed in the center. I would like to see a little less negative space to her right. A simple cropping job would fix that.
And just to add, I checked out your Flickr site and you obviously know composition real well. This picture: Natalie on Flickr - Photo Sharing! is composed beautifully. Great use of the rule of thirds!
