I've done a lot of designs.
Graph paper and I are old friends.
Here's a few design sketches from the last few years (and decades, in some cases).
Some stuff is on a list to get made, some stuff will never see the light of day, and others have been cannibalized into other designs.
The designs are a combination of several different fictional works I've been tinkering with for decades. I like how the pilot is enclosed in the torso of the heavier armors in a kneeling position.
