I recommend you to pause on the animations for now, and first perfect your character.
I see this chest plate and think it yields no relation to the underlying shape, make it accentuate muscularity more.
Then the arms go into the outpointing part of the shoulder pads, but they come from the torso as a whole, try to look at the shape of a human shoulder girdle, and then apply your shoulder pads to that, so first draw the creature, before drawing it's armor and making misjunctions in the joints.
then the knees should go up a bit higher, and the main bulk of the calve could be placed more inwards, right now there really is a bulge on the front side of the leg which isn't supposedd to be there. So globally, although alien, look at human(oid) anatomy more and redesign this guy for the majority. Then start thinking about his armor again and make it make more sense in both shape and attachment to the body.
