I would've been cool if you had made the rocket from the tower which was already there. Nice entry and good luck!

Author, Chalty had a good idea...it's not too late!
PS: The reflection would be foreshortened a bit.

Nice idea. And also agree with both.

The shadows are way too dark. Also the perspective of them (especially the left side) is way off, they're cast on the ground as there are no obstacles, so it shouldn't cover things from the hills.. Now it looks like the shadow is both out of perspective and also miles long.. Scale them smaller and use the perspective tool

are those shadows or silhouettes? either way, they don't really work with this lighting
