Could you describe the "not so perfect technically"? 
I'd love to know the opinion of other people!

No problem. I think that the surface doesn't look so good, and could definitely be improved, and something is wrong with the reflection. I think that the planet overlaps the terrain reflection in one part, and that reflection perspective could do a bit of tweaking. Perhaps it should even be brighter a bit.
That's what I needed I'll try to improve it later. thank you! :*
