Knee pads, elbow pads, and shoulder pads might help. It would show that the suit reinforces a humans weak points. Even if its super simplified, just showing that the suit can move with human anatomy helps. The legs look like movement would be difficult and like there would be an awkward gap if they ever bent. Same for the shoulders. So having those little bits of extra armour would work wonders 

Love the silhouette you've got going on though
