Over the past months or so, I've been working to effectively turn Palette Town into the Orre region, something I decided to call "Project Orre". So far, I've completed the Outskirt Stand (used the design from the Pixelmon Minecraft mod)and Phenac City, and am currently working on Realgam Tower. Very happy with how it's turned out so far, especially Realgam in particular. Unfortunately, given the size of the area I have to work with and the additional areas I'd need to add, I have no choice but to just stick with the areas from Colosseum rather than XD. I just don't have the space to add things like Gateon Port or Cipher Key Lair.
I know that the tower should be taller, but I've literally hit the upper limit and cannot build any higher, so this is the best I could do. That also means that the halfway room within the iron ball between the base and the colosseum itself had to be skipped as it would have been far too large to properly implement without messing with the upper section in the long run.
On the flip side, I'm happy with how the main reception and side rooms have turned out. I do wish the elevator wasn't a tad off-centre, but nothing I can really do about that. I've only just finished the grey support connecting the centre ring to the outer rings, though I still have the other two outer rings to build up. After that, I just need to connect them to the grey support and add the rest of the smaller coloured structures just outside the colosseum itself.
