Brilliant capture, but something on my monitor seems of with the colors.

The only reason I didn't give it a 3 is that some cropping to tighten the composition and some delicate dogging to separate the background from the middle ground (cropping would have dealt with the foreground need separation) - would have bumped it all the way to solid given the amount of drama and action of the dog (these dogs go full tilt). Hold a sheet of printer paper or black cardstock with a rectangle cutout and see.
