Looking good! I watched these without sound (no speakers at the job) so if there was a voiceover I didn't hear it.

Some things that I think could improve your project a little:
I think if you could maybe clear some of the standards and things out of the way, it will make it easier to watch for sure.
Maybe move the ads so they don't break up the text?
Maybe add a glossary of terms? I've had a lot of youth kids and ammy riders who have asked me what self-carriage, splitting the hocks, and so forth means.

Great start. I had thought about doing something like this and you totally beat me to it. Cute mare by the way!
