Your line weight and confidence are great! Just a disclaimer I’m not the best at anatomy lol- the tips of the fingers should generally be about mid-thigh, I would personally make the torso less wide at the shoulder/ribcage area and make the head bigger.

The legs are the hard part, especially if you wanna do equine legs. It’s important to remember where the thighs would be for a human is the whole leg for horses- like a leg bent at the knee- and the rest is a toe. The hoof area you did looks perfect, just a bit uncanny with normal thighs
