I would have to concur with ImpFighter. Here are some screen caps:

Replacing the sky area around the Slave 1 could help it stand out more. Another thing: what about those 2 stormtroopers that were watching Solo be loaded aboard? Would we see them walking away on the platform? Would their bodies be somewhere in the following scenes?

Also, would the buildings in the shot about need to be altered to match the ones in the new shot below?

I would also ask: should the buildings in the "Slave 1 taking off" shot be angled the way they are (as opposed to more level, as indicated by the red line)?

BTW, love those new clouds...
