Very neat build! I like it a lot; you obviously command a vast knowledge of the Star Wars universe, as is evident in your creation. Jus one question, though; isn't it against Galactic Law to keep sentient creatures in a zoo?
Man, this is totally awesome! I really love all the nice details you have in this diorama: from the poor Gungan about to be eaten by the Rancor, to Vader and the Emperor shovelling Bantha, em, nevermind. :P Overall an excellent job and congrats on MOTD! 5/5! :-)
Very original piece of MOC and with some inventive buildind such as the rocky hill and Jurrasic Park like electric fencing. Well done and a deserved ranking in the context of what looks like a very productive week.
