Great piece! I saw that you're looking for some constructive critique so here is mine:
Although the planet is very well achieved, form a light and shadow point of view, it would be much more interesting if the background Universe had more stars...or at least brighter to accompany the planet's light side. Plus, the ring could be much more glowing or strong, to emphasize it! (Although this soft brightness creates a mysterious and interesting mood).
