Without reading any of the other replies which might affect my choice...the 2nd one does it for me. :)

ok...after reading :P

I agree that though the composition is better on the second one, it lacks some depth in colour department. What do you use to edit with? I use Photoshop and the best tool I've found in that is a Curves Adjustment Layer.

The image attached was modified in about 1 minute with a curves adjustment layer. Its not what Im saying you should do with the image, but an example of the effect you can acheive without messing about with selecting one element of the image with a selection tool. I hope you dont mind me fiddling with yor image ;)
