Thanks to all who voted - I was at 5.5 for a while, then I started to slip. Still, I scored better than in my first attempt at a challenge.
And thanks for the comments. The bike was not mine - it's being slowly dismantled round the corner from my house - both mudguards have now gone...
I actually rested the camera on the ground to get the shot and as I could not see what I was shooting, it took me a few attempts to get something I liked. I took around 30 pics altogether and I selected the one I thought was most effective. I went the b/w route to give the image more 'mood'.
