This is a discussion on My latest equine photography :) within the Horse Pictures forums, part of the Horse Pictures, Videos, Artwork, and Contests category
I've been doing quine photography for awhile. I don't have my new camera yet, so the quality is a little bad, but here are the photos from the last horse show I attended. :)
You will definitely benefit from a higher quality camera. Your angles and eye are great, but would be even better with the less blur and higher clarity that a better camera will offer.
