Do I have this Spaceship properly Proportioned to the trees in this scene?
I’d be more concerned with how the ship was shot. It’s soft and fuzzy/grainy. Between that and the shake in the ship (not sure how you added that, but it’s distracting), it looks very much like a miniature that has been shot up close and out of focus. The shake doesn’t move naturally against the background, so it almost looks like handheld shake rather than turbulence.
That, and the key is losing entire sections of the crystals.
