Interesting shot you got here. Nice use of selective desat, it really draws your eye to the car, but the very bright water slide to the left is distracting me. It's almost as if you have two main subjects. Other than that, it's a nice pic.
A tad bit busy for my taste. Maybe a tighter zoom to block out un-needed elements would make it more effective. I'm not sure what the selective desat is supposed to say here. At 640 by xxx it's not very effective. Might work at 8x10 though.
