This image is overall a bit blurry and as some say "flat". Perhaps more post-processing (maybe high contrast) would have made this a 'good blurry shot', but as it stands now this picture is too greyish. I do like the framing however, which is the most important skill a photographer can have.
i had given this an 8. i suspect you're gonna get hammered for the blur, i personally feel it adds a sense of realism, drama, urgency, and makes it all the more dynamic. it almost feels like one of those scoop spy shots you see published. i love that there are very few real colours in this picture, that the silvers and greys go together really very well. well done.
