This is another good example of panning motion, but the composition is suffering because of the framing... The feet are providing the motion in this photo and they are not visible... I think a wider angle could improve this idea significantly. = 5
Here the motion blur works really well in my opinion. Really enhances the action, while keeping the main subject recognisable. Good composition as well. Best sports shot in this challenge.
Great motion blur... I'd have flipped the photo so he was running from left to right. Possibly a tighter crop on the left so he is about to run out of the frame would make this look a lot more dynamic. Perhaps a boost on green in shadows, and a decrease on cyan in highlights would help as well.
