Thank you very much, fellas!
@Hahmo: The reflection is actually pretty easy to make, just use the LFSviewer to do a rough 'reflection', paste it into photoshop, flip it vertically and erase any unnecessary parts. Lower the opacity, add a gradient mask and maybe a distort filter. The water effect on the tarmac is custom brushes.
@andRo: I actually desaturated the image a bit, as rain tends to do that and I like the look, but yes, I might play around with the levels a bit more.
