Very cool! I like that you put the crew compartment all the way in the rear. Admittedly, I haven't given too much thought as to what a traditional bipedal mecha would look like in the universe, but something smaller in scale intended for light infantry support would probably make the most sense, seeing as most legged and wheeled vehicles would be outpacing them both in firepower and movement speed.
i can continue to detail this design up if you'd be interested. and keep up the good work man!!
Cheers! Feel free to.
