Wow! A113 that is looking incredible! I can't wait for the final product!
Just out of curiosity, what do you have left to do? Like, are you planning on doing 3ds for Paradise Pier, or at least for what's around California Screamin'?
EDIT: Sorry for all of those posts. I'm not sure what happened. I was getting an error on the forum. Anyways I've deleted them now.
A113 i think you should add some more detail to the tunnels. On Cal Screamin one side of the tunnel is only partial, on yours it looks like the entire tunnel is solid (and hexagonal). also judging by what I've seen so far it shouldnt be too difficult for you just to add a few ridges to the tunnel.
