Great photo! The only this I might suggest is crop the right just a smidge so that far off rider is gone. Her little blue coat and black helmet is a bit distracting from an other wise beautifully classic hunter photo!
ill try to edit them out in a later redo...i think less space off that side looks almost awkward in a photo like this, you want the horse to be able to 'go' somewhere... my personal opinion but thank you for bringing that to my attention! hadnt noticed it before! at a show park with 4 rings behind this one its lucky that there is only one!
