Pretty build, If there was one thing I would suggest, it'd be altering the weapon setup since this thing effectively sabotages itself by shooting its own missiles down consistently, and (most) of its armament isn't all too effective.Maybe switch the knee missiles for lockon/pulse ones, and replace the shoulder machine guns with a slower cannon type or laser weapon, and reduce the head cannon to a single dual array for PD defense to save space? As it stands it can't do much damage on its own
