a note to myself regarding my concept and artsitic ancestors

Right now, we're being asked to give a presentation on our art(how beautifully kitchy). We must include our artistic ancestors and our concepts in their entirety. My concept is taken care of. Roughly it is this:

My art centers itself on the concept of a unifying force that moves through my life. I can't see it. I cant touch it. I can't smell it. But I swear I can hear it.It's musical. Though it's not so much a tune one could whistle or hum. It's soul-ly a tune for the mind. It permeates everything in my life that belongs to me or to nature.
I dont hear it in my economics class or from this computer as I sit here typing. I hear it in the rain and the sun on my face. I dance to it on a horse's back or swimming in a lake. But it is through the horses that I can hear this tune the clearest. Every prancing step, turn of their head, or snort of their breath. It charges me full of so much blinding ecstacy that I feel I'll burst. This happens to me every single time I go out to Fox Fire farms, the horse stable I work and ride at. Hell, I practically live there.
It's playful and sultry, melodic and lilting. These traits in the unplayed music of hapiness I hear from the horses are what I attempt to convey through my work.
From the technical aspect, I use shapes, commonly found as shadows on the horse's form, slightly abstaracted and repeated to bring a certain level of brilliance and movement to the horse figures I depict. These patterns further liven up the horses for the average viewer, who may not delight in the simple figure of the equine beast as much as I do.

And I could go on. That amazing song fills me with true ecstacy.

But it's the ancestors I'm having so much trouble with right now. My work is wholly original. Well, no work is wholly orginal. But name for me a list of artists working with horses beyond the concept of "oooh here's a pretty pony, lets paint it to look exactly like it is and sell it." You can't. There's a girl like that in the junior level at my school. It aggrevates the hell outta me. As a small aspect of my work, I enjoy the challenge of continually pushing beyond the idea of "equine art" All that brings to mind are pictures of oil portraits hung up in rich people's houses.
Deborah Butterfilrd is one woman whom I suppose I must credit. As she is one of the only other artists I know about that has ever bothered to try and create truly orginal work, that just happened to involve horses. The horses themselves are, of course, my greatest ancestors. Music, as it enters through them becomes inspiration. But That's it, Unless we may broaden that tune to simply be summarized as nature and all of the beauty it holds. But Shit!
I DON'T KNOW WHO ELSE TO USE AND WE HAVE TO HAVE AT LEAST 4 ANCESTORS!!!!
