There just isn't enough motion in this pic to really meet the challenge, he also seems a little squished into that letter box frame, which is unnecessary.
I do however love the shallow dof in the field lovely.
whoa! That's either a mare in foal or one that needs to go on a diet - or get ridden for an hour each day, even if only a walk, for 5 days a week for 6 months.
This is a beautiful animal and the image meets the challenge well.
Unfortunately, for me, the heavy black border and the close cropping
seem to box the critter in pretty tight in the frame, taking away
from the main attraction.
Still, the yellow field and the gorgeous brown coat of the horse make
the whole thing zing.
