No, quite the contrary, that motion blur is perfect for this image. When I said the image felt flat I was talking about the processing. Maybe a little more local contrast (without blowing highlights or losing detail in shadows) or a more pronounced vignetting giving more emphasis on the car. Again: the photo itself is very good. It's the post-processing that would benefit from some more work. However, if you're a purist and believe the photo should stay the way it was produced by the camera, what I'm saying becomes irrelevant.
