That hexagonal granny grating seems perfect for all sorts of sci-fi terrain purposes! Heck, just spraypaint it grey/silver/grimy and lay it down on the table for instant sci-fi flavour. (or flavor, if you're a Yank...)
Going to have to keep an eye out for that stuff at the local craft stores!
The loading ramp looks good, and especially nice that it actually folds the way it should.
