@Shroomblaze: Probably because it's a recolor of the default building.

The smoke is the reason I unsubcribed

Hey I honestly think you should be getting a lot more credit and subscribers for this building. It's really nice work. I'm surprised this doesn't have more than 1,000 Subs already. My only criticism though is that there is a lot of steam and smoke coming out of the smoke stacks. May want to reduce that down a little bit. Nice Work though! :)
