He or she is beautiful, I love any equine animal! I can see where you're coming from for the challenge, I think the most common jobs for these poor animals is having kids on the backs of them going up and down a beach in the hot sun.....a far cry from the useful jobs they were used to. Well done though, a lovely pic.
She's a sweet old dear. No use for her anymore than just having the pleasure to see her happy through her last years (or is it a he?) Many voters won't see this animal as being obsolete I guess, but I've a mind of my own and I'll rate her/him an 8.
How's fat and happy. I think a more flattering shot of him would be from the side. Although it looks like he needs grooming, I do believe that he is smiling for the camera. I hope he doesn't know you are considering him obsolete.
Looks like this one is glad to be obsolete. Not sure how I feel about the vertical bars in background. That animal could use some vertical stripes itself. Man, that thing is fat:)
