A very good action shot, just caught the moment well.
Now I assume you're going to use this for one of the Club competitions.
If so i would seriously think about cloning out the red post on the left. I know it's an integral part of the horse competition but from an aesthetic pov it does draw the eye away from the horse & rider. Just the sort of thing some judge will comment on & downmark the image.
Adrian.

quite like the composition here, although I think the basket in the background is a bit distracting. Also (wearing my pedantic hat) you've chopped off the bottom of the chain mail.
Apart from that - good.

Contrasts well with the background. 2 small points, the bottom petal has been cropped off too far & personally I find the copyright text intrusive placed in the centre.

just to add my pennyworth, I like the side view of V3, and the lack of space on the left is not really a problem for me. What jarrs slightly is the lighter blue block top left ( out of focus sky?).
Because it's lighter than the rest of the image I find it tends to draw my eye away from the flower. makking it a similar depth to the rest of the b/g would be better.
