An interesting image. I like the clean/polished chrome on those bumpers and the reflections are really good.
Speaking of which, looking at the reflection on the hood it looks like there was some nice photogenic weather that day so I'm wondering if there was an opportunity to include more of that in the shot somehow. I'm thinking perhaps a crazy angle like lying down on the ground and shooting upward so that the chrome and the sky are in the shot. Probably wouldn't work if I actually saw what I am talking about in the viewfinder but it might be something explore at another time. Anyway, I bring that up because the angle you took for this was pretty conservative and with other people submitting similar things you want to really make yours stand out and having a bold angle might have been the trick. Not that I speak from experience since I haven't won anything so take with a grain of salt! :)
