If you are wondering why some angles don't match, it's because the skin itself won't allow to do so. I even tried to retexture the skin's actual file in paint 3d and it gives me the same problem. Some sides are connected so when you think you are editing just one, you are actually editing the other too. Fortunately it's not something that you notice at first sight. Especially if you are trying to get all their gold in the monument :D
