I think this is more interesting than the standard car shots of the same vein. It's cool how the sky almost looks fluid, as though it were melting away.
That's the sort of shot you'd have to expect trying to take a shot riding pillion and taking it through your helmet! Only kidding. Great effect and well done.
Motion alright, but you could have done better on the abstract. Maybe a different crop would have done the trick. I think you should have left the motor out. Like the left upper halve.
