This was a use up of all my bits of scraps. The man structure is white foam board with the paper stripped. I also use bits of 2mm balsa wood to create the depth on the panels. I wanted a 'cloud city' feel so painted it a base coat of grey then dry brushed with a light cream. I then added some weathering in black pastel.
Its simple but effective. I wanted to keep the structure tight looking. My next project is a much larger Star Wars piece for 3.75 inch figure range.
