Hmm, where to begin.
Let's go from top to bottom
Anatomy/Basics.
Horns- They look out of shape, almost like they are more of a cloud rather then solid horns, try to make them more slender and look like solid curved bones.
Head- The angle looks word with the rest of his body, like he's standing with the front to us, but the head at a 90% degree, which, trust me, looks weird and hurts like hell.

might be an idea to fix with turning the torso more towards the side.
Left arm - Too short, need the elbow to be more visible.
Right arm - He has no elbow on it.
Chest - As said before, turn it to the side more or turn the head more towards us.
Left leg - It looks werid with the anchor depth there , an idea is to make the kneecap more higher due to double kneecapped legs.
Right leg: Looks okay, just the hoof look odd with how the feet/Leg angle is.
Let's begin there.
