Fantastic detailing both inside and outside of the base. The only thing I'd say to improve upon is that the land between the base and the cliff is a little too barren compared to the rest of the Moc, but it's still spectacular in it's own right. How did you achieve the half circle shape inside the base? Please check out my Acclamator Assault Ship when you get the chance. Thanks!
You really are the master of SW Clone bases. this is amazing; I love how those two platforms stick out of the cliff face. It must be hard to find a viable background for a MOC this large but it might help with the presentation. :)
Excellent build, but I agree with JS Can. Utapau was a Separatist-controlled planet, so it wouldn't really make sense for there to be a Clone Base on it. Not that that takes away from the impressive build though. The extreme amount of detail blows me away.
