Hey Commander Smelly,
These came out pretty good. You have some nice paint apps here. I especially like the trooper with the orange forearms/hands.
The "rocket" trooper looks good as well. I would suggest painting the other part of the on his face gray as well. You might also clean up his left arm.
Like the gunship, the clones aren't overdone and you kept them very simple. I'm glad you're finally taking on the custom hobby. You're off to a good start.
