I'm still working to rearranged it, i have another empty room to renovate another cave.  Will make super cave.

Nice! Is that your ceiling?  Maybe its a good idea for my aircraft room.  I did think about that idea, i need to improve the lightings to make the blue skies more vibrant. The one shown on my main hangar have crappy lighting.  My android control LED lighting sets from Banggood.com is on its way hopefully brightens everything.
