no1 is a nice affect just a little more out of focus on the right would have been better as the headlight is the first thing I'm drawn to and as it's not in focus its awkward, good idea just a few tweaks and thats a cracking banner image...
no3, the trees are slightly distracting but the composition is great.
no 6 for me, very dramatic, as said above location doesn't really shout I'm an angry bmw, some nice twisty roads in the background (and even feeling brave some 11's on the road) of that would have worked really well, lots of potential.
