Where to go?

So really unsure if this works or not; cut too much away (or rather grabbed too little as this was an in motion shot) or too much or the wrong angle?

Been messing around with a few different angles and perspectives in shots so a bit out of my depth to know if this "works" or not; it might just be that this angle works but the background lacks any real point of interest/draw for the viewer.

I think this angle would work as a closer crop - focusing on and drawing the attention to the eye of the horse. I'd cut out most of the rider, just showing the hands and knees basically. In this particular image the rider is a little off-balance, which throws the pic off. If you have any room lower in the pic, I'd retain some of that, around mid-calf on the rider if possible.

Horse shows are tough to shoot - you did well really.

Cheers,
Chris.
