very much like australia needs to have redder dirt
what??? erase... clone... why? I thought the fire clone and water clone looked cool! and you are supposed to have deco on so you can not see the clone.
Add pipes in the tunnels, erase the clone. and add clone stone, concrete, etc. in the minecarts.
As for suggestions you could add a storage facility as where they are puting all the oil and you could add a small processing plant underground. (doesn't have to be working) just like circles of oil for looks and pipes (also not the real element pipe, unless you want to) going up to the storage place ect. Just get creative!
there are now minecarts!!!
Very nice! I like the landscape. Just dont forget to add the minecarts! I would like to see the finished product. If you want you can give the finished id and I will check it out. ;) +1
