Here are some pictures of the horses I used to work with - hope they are kinda what your looking for --
This is Obsession, Pure Arabian Gelding
This is Candy Cane, My Lease Horse. She is a Grade Mare, meaning shes like a 'mutt' in horse terms
This Is Dakota, a Quarter Horse Mare
This is Elvis, he is a Off the Track Thoroughbred.
This is Ellie, Shes the same breed as Dakota, QH Mare
Hope this helped you out at all. Let me know if you have any questions about the horses I posted!
AND sorry some of the pictures are bigger then others. I did not feel like resizing them all..
