I actually use my mother's camera. It's a Nikon D5000. It does quite a bit of justice to Moe, I'd say. But horses like my mare, Sadie, just aren't photogenic. She's a major fatty, but Moe somehow keeps himself conditioned rather well. He's always been like that, too. Perhaps it's just his hot-headedness that keeps him running around like some sort of crazed lion.
Also, on the topic of an Arab x Appaloosa, I believe they are sometimes called an Araloosa. Just one of them fancy names that pretty much mean nothing. (Like a Labradoodle dog, or a Border Jack.)
I've never heard of the word Sarmadee, but I believe Sarmadi means something in arabic. I saw it somewhere but I can't find it again.
