Occidens

Beautifully done. I rate it 3.5-3.75 stars.
2.5 stars is OK 3 stars or above is Good 2 stars or below would be considered far from finished.

I admire the panorama view of that rocky wall on our right hand side as it swoops towards the left. This wall creates a sense of perspective, something I do not usually see in most photo manipulations of nature. This one point perspective technique you used for the wall of rocks with the arch draws the viewers eye towards the duo habitable worlds.

The northern lights are quite beautifully placed over the world which gives the viewer a sense of tranquility. (it must of been quite exciting to be a citizen on such a world, you see a blue marble and a baron moon with some auroras).
The city lights are quite beautiful and adds a sense of depth on the surface of the planet or moon.

Some advice to improve: the clouds on the planet could use significantly more detail to add some more depth in the pictures. The rocky wall although from a distance looks quite beautiful too could use some more details up close.
Overall great work.
