I love martini's and this photo has good composition. However, it feels more like a snapshot than an artistic photograph. It's probably the strong lighting.
Impressive.. more impressive if the shake was visible. I would like to see some movement maybe tilting it a little bit and then trying to picture it while it comes back.. :)
Oooohhh, they let you take photos inside a real casino? Cool! Nice work on the set up. Flash is a bit intrusive but nonetheless, this works well enough! :)
