I think a BW conversion on this or even a gradual fade to BW would have been great (Start off in color on the right and gradually desat as it goes left). But, I'm not sure if that would have been legal editing. Would be cool to see, though.
i like the composition and i like the processing a lot. the problem, for me, is the subject. it's a car so it doesn't really show much 'movement' from one frame to the next. clearly, it's time lapse photography, but in a way, it's static. my lame example... maybe if the driver had been waving their arm out the window so that it was in different positions as the car moved along in each frame.
Sort of accomplishes the task but brings no more to the table. Shame, really - apart from being a magnificently maintained old vehicle, it comes over as a wee bit bland. Still 'n all, you have to have at least 5 just for giving the sc something to try out their new rules on :-)
To me, the subject is a little plain, I think maybe if the car was a bright color Red for example, this photo would have "popped"! Still good idea and comp.
I like your image, but I am not crazy about the vignette. It is more of a distraction than an enhancement in my opinion. Overall you did a nice job blending the image. Still, that vignetting is a deal breaker for me. 6
