A very impressive use of MojoWorld, nicely coloured and dramatic.

* A bit too much curvature for me, which I might have fixed by using Photoshop to straighten up the left hand eroded column. But the ability to do that without fuzzing assumes you're rendering to 4k or or are willing to overpaint any resulting blurry bits.

* I would also have bushed the right hand low cliffs with a soft red-orange brush, to suggest just the slightest light-bounce on them from the orange clouds.

* I might have added drama by adding a dome city on the right, and then had the ship going out from it, bravely heading toward the red cloud - perhaps on a mission to investigate or neutralise it.
