Aw! Cute!! This looks like a character from Dr. Seuss or something with the colors and whimsical shapes in the antlers and tail. I think it's looking a bit flat, maybe you could push the values darker and lighter in some areas and start establishing different textures. Unless you were going for the flat children's booky-look, then I'd say it's looking great :) Really nice job!! I like this design!
Its a jackelope!I agree with the previous comments. Value should be pushed. Also, watch out for the direction of the light source. He has a highlight on his back and on the fronts of his leg. You could still keep those values if you changed one of them into some sort of rim lighting, but I would emphasize a more prominent light direction.
ARE THE HORNS MAGICAL??? I wish they were, or looked like they emit some magical light for some reason. Just think about it. I would say he looks like he's just pasted on the page rather than sitting on something. The are of concern is his back legs are bubbly, which makes them look like they are bearing no weight. He's so cool though, nice job!
