Great picture, and love the detail. The top right corner (sky & car) could have had a bit of attention, but still a 9 for me.
In my opinion: subject - 10, composition - 10, process - 8. Overall - 9.
I really like the point of view. There is a lack of structure on the car in my opinion.
Perhaps the upper right corner can be added from a single image. You should give it a try to get rid off the pruple sky :-)
like it, but the blue sky is a little bit distracting
