This animates really, really well. And I love the various weapons. I can't really think of any critique in the way of the modeling. Top notch quality.
The textures in some areas do seem a bit too clean, though. It's almost as if they just have a colored blinn or phong applied. The area between the legs looks good and textured because of the slight grittiness from the occlusion, but the pauldrons seem a bit flat-colored. Maybe a little grit and dirtiness in some areas would help. Maybe some battle scars. You could also bake the occlusion in as a dirt map to add a bit more variation (although that doesn't always look better) . Nothing too much, as I can tell that it is textured, it just needs to be a bit more obvious.
