duuuuude i LOVE this
i have something similar in the works, a SW conversion, but mine is still missing a lot of parts. i didn't want to use the cobra head panels on the outer circle so i been thinking of replacing them and just adding more canons all around in place. or just cutting sheets of styrene to cover the empty space behind the cobra panels.
i really like how u did the computer screens and adding vader chamber underneath.
excellent job all around.
