If this is your first Dio then all i can say is that you're on the right track. That "crate" you have with the Hoth trooper is pretty cool...i'm actually looking for something like that for my Mos Maa'eli diorama. If you don't mind me asking, what did you use for that? I've got stacked barrels etc etc but i need crates.
The figure you've got in the prison looks pretty cool, good job.
