I was so annoyed getting an American Delta base in a Dekabase box (thanks BAsia) so i felt justified in what i did. Lots of changes made. I changed the blue tint for the ridged windows and painted all the ridges silver. Added detail to the 'lower floors'. dirties it up with Gundam Marker and Alcohol Wipes (looks waaaaaaaaay better in person) etc etc
Still figuring out how to add the main entrance, which i will later.
The only things I think the Deltabase lacked were the logos on the building signages (megazord shoulder) and the gold reflectors on the Megazord Chestplate. Of course I can argue that my version is now actually better. LOL
