I would think that the light on the street in the foreground makes people curious when they see the thumb, so the image gets a lot of views.
I like the light reflections, the swath of the bike lights, and the complex background is interesting to see.
It is like the street has just been splashed with rainbow. My first thought, like Quiche below, was that there was too much foreground but then I decided that the beautiful street colors are my favorite part of the image. It would be cool to do another shot like this with the pavement lighting as your main focus.
Colors are great, the bike lights are cool, and it gives a good feel for a Las Vegas street scene at night. There's a little bit too much foreground in it for my taste, but I still like this a lot.
This photo reminds me of a street in Wellington NZ... Minus the Palm Trees is the buildings and lights look alot like a shot I have. Very colorful picture
