Hmm-hmm...
I'm excited to see yet another entry in the "Goblin building" department from you, Skymarshall. This one seems to fit the bill; simple, effective, fitting in style both to Warcraft & your other Goblin buildings... With some zany Goblin quirks.
I am a big fan of the rocket, though if possible I'd love to see it spin faster during Stand - Work (or slower during Stand, I suppose); would help make things more clear (since those door particles are awful small). As the base-level T1 "Barracks" for the Goblins, there's really not much more that this thing should have; it should make an excellent "Training Shack" for my Goblin Bruisers, Saboteurs, and the like. : )
I begin to wonder if that Laboratory roof will look overused... I suppose it's a very fine line between "aesthetic tie-in" and "aesthetic over-use". Seeing the whole set will really make the line more clear, I guess.
Keep it up! Let us know if you need ideas. : )
