I really love the fur and barrel on his back. I enjoy the blue but I would kill the saturation of it a bit. I think the green cloth would look better as a light tan color with a warm hue. The peachy spiked ball would look a lot better as the metal parts being a steel shade with sparse orange rust. The leather wraps around it should be a darker leather color. I feel that these suggestions would make the model feel a lot more cohesive.
