Nice use of a high angle to get a sense of the overall scene. I also like the colored lights on the machines. I would guess there's another light source as well, from the colors on the figures. I like the intent expressions on the people.
I think I would have cropped out the balcony in the bottom right corner and narrowed in on the bottom & middle row only if it had been possible -- overall I like the photo...
Technical: Fits the challenge. Exposure pretty good (tough with those machines) Composition is extremely interesting, but the bottom right corner is distrcting. Focus is good. Lighting is even.
Personal: Creativity is visible mainly in the angle. Not exactly a new idea though!
an interesting angle. wish the lines of machines lined up with the edge of the picture. it would make a more pleasing composition. The odd triangle in the corner is distracting
I like the picture a lot and it certainly does represent money. On a side issue -- I would be careful with this picture on the internet as you could easily get in trouble since I believe taking pictures in most casinos is illegal and if anyone in this picture should see themself they might not be too pleased. Back to the issue at hand -- great representation of the challenge. Good cropping of photo.
