Horses and their legs

If there's one thing I cannot seem to get right - it's drawing horses and legs on horses. I'm learning slowly, but hate doing them. Here are two I drew earlier today for a book (Pearson Education). They look very generic, but I'll keep at it. I also tried to have them behind a hedge, a wall, even in some long grass - but no, I have to learn. Avoidance will only catch up with me! horses
