While most would likely say that the design is either clunky or not appealing as a mech, i love the design. Looks much more like what i'd expect in a mechanized walker. Arctic paint makes it look even better
I figured that in your description this would be a good guy weapon, considering what you said in the description.
Just that to me, I could imagine it also being used in Strike Witches, where those evil mercenary guys would be piloting hundreds of them in their quest to conquer the world, and the Joint Fighters fighting against them.
