Good choice of brush/es for the ears, it gives a really fluffy feel. I also think you did well with how the hair falls between his horns, It's a lovely poof of hair. Nice call to add the lighting the way you did on the horns, instead of adding it in a smooth streak along the length of them- it helps add to the shape and texture to help it feel organic. You've got the shape of the nose down really well, and I like those teeth a lot. The eye details are a nice little touch too. Maybe try adding a little lighting to the general fur on him, like on the bridge of his nose and his far shoulder, cause it's flat compared to his longer hair and could be a good chance to add a little more texture to the piece.
