These scenes are exquisite, really.
I particularly like the walker, as it looks like bleeding edge technology. Really bleeding! Like gerry-rigged together to be a fighting machine in the worst, more desperate circumstances. Your use of colour, or lack of, sometimes, is superb. The attack fighter is a delight, too, looking like some dangerous, ultra-modern gunship. Juxtaposed next to the old, almost decrepit landing pad.
I love the brick built weapons, too. They show your devotion to small details, which is admirable and lovely to look at.
