24 Hours of Flickr - Candidates

I need your help! The 24 Hours of Flickr day has passed and I took a handful of photos which I must now choose ONE to enter into the contest. A set of photos will be selected from the submitted photos and will either be printed in a book or used in future Flickr events during the summer. I was rather excited at the opportunity to submit a photo, so I took a few photos in and around the poker tournament yesterday so I could submit a photo. I've narrowed the selection down to 5 photos and would like to garner any opinions on which one I should select. Here, in no particular order, are the 5 photographs:

487526658.jpg
487524774.jpg

If you have an opinion, please leave me a comment here or on the appropriate photo's flickr page within the next couple of days. I'd like to submit a photo fairly soon.

Thanks! Heraldk
