I love this!

A few points:
I didn't notice the planet until I saw some earlier wips. I think it's hidden by the glass reflections, and has values and hues too close to the ship's.
The door doesn't look spaceshiplike.
The vertical vine left of the door, and horizontal left of that and above the guy look too straight and simple.
The general light looks too even, and doesn't really read as a confined space. Might be better if there were patches of topdown light. I'd mostly darken the image top, parts of the floor and 'tabletop' (left corner mostly).
