Dear OP, Comparing the B&W and the "color" version, I prefer the B&W. In fact before you posted the reply saying that there is a B&W version, I was thinking of asking you to convert it to B&W, as the few points of color were not adding much value.
My second thought is that there is too much in the picture. Specially to the right and left of the two front pillars. So you might look at a cropped version of the photo and see if you like that or not. If you do not want to crop at all, then may be you can go back to this place again and try to capture the same scene with just one car parked. Think about that composition.
Third, I think it is a completely available light photograph. So if you have access to a tripod, then you might want to capture the same vista with a bit more exposure (or try to add fill light/exposure in post processing) to bring out a bit more of the shadow details. Or you may want to wait for change of season and see if the angle of sun does some trick or not.
But you have good eyes to see that such an everyday scene can also be captured. Enjoy!
