That is an amazing drawing. Though, from an engineering perspective, the "ankles" and "feet" are way to undersized.
Imagine walking on fresh, deep, powdery snow in your bare feet, or large boots doesn't matter. You will sink, with ever step. That is probably what would happen to that behemoth with it's tiny chicken feet.
Now imagine having on snow shoes. They are huge, and well you don't sink as much and you stay on top. Your mecha just seems off balance, but that is just my opinion.
i like this very much. your main armament is well thought out, as a 50mm autocannon has multiple punch capabilities. the 7.62 however will need more like 4000 rounds in the hopper to be truely effective. what armour type you got running? void is a space-reliant system, and chobam is too heavy. you just got thick steel and titanium going here?
I´m so fucked up by now...i thought i culdn´t get more depressed when i saw meckanicalmind´s gallery... well you can always learn. this is gonna be long night for i´m about to fave this whole fuckin´gallery right now, i think...
