This excellent Classic Space MOC by Bongobert successfully combines the essence of Classic Space (blue, grey, trans-yellow, bumblebee stripes) with a very modern aesthetic.
I really like the engine pods with the reversed jet engine piece and the big flag; and the cockpit has a kind of insect-like attitude which looks particularly menacing as it hovers overhead. Apparently it does this to pew-pew you with its big chin mounted gun. Ouch.
