try and make a basic human form, apply some armatures, with the rotation restraints that the basic human body has. When everything poses normally, parent the different body sections to armor that protects it. Other words ball joints for shoulder, elbow, hands, knees, so on . When you can pose the test body,then add the armor, making sure logical rotations around joints is achieved. watch the irom man movie. That was a very good example, if not, google medievel armor

Otherwise it's an interesting design and project.
otherwise, proportions are ok.
and fallout style
WOOT! Iron Man!
anyway, it looks great except you should move the knee joint up about 20-30%.
