Those are well done!
I've got a suggestion. When you are done with that map, cut out the shuttle, PC ship?, speeders, crates, etc. Glue them on poster board (actually glue them on the board, then cut the shape out with a utility knife). That way, you can easily plop them down on a new map saving drawing time. It also helps if you suddenly need to move a parked speeder to another location, a PC decides to move a crate to block a doorway, etc.
I've got a draw full of speeders, ships, crates, and other sundries on poster board from an old campaign.
