I think the first thing most people look at is the ribs or the hips but my eye is always drawn to how prominent that shoulder angle is...for some reason Roscoe's struck me and so do the horses you posted CheyAut.
Chey, I am so sorry for the lose of your beautiful girl. At least you can rest assured that she led a happy life while it lasted. Rest in Peace Radiance. She definitely was a beautiful girl, as beautiful as they come.
Here are some more before and after pictures of a horse that use to live at the stables I boarded at. It's kind of an extreme change in the negative direction, but he did improve and has returned to a showing career but I don't have any recent photos of him.
His barn name is Trinity. He's a pure Arabian. This was him back in the prime of his showing career.
And here are some pictures of him after he stopped showing and was sold. This is what he looked like when I first met him, he had just suffered a really bad case of colic and had lost weight. He improved later on and regained weight. And yes, he is cribbing in this picture... Darn Cribbers. Trin is a very sweet horse and was one of Vega's best friends.
They recently just sold him where he is making a nice comeback on the local show scene
