1) Wow! You can definitely do good stuff in 3D.
2) Not quite convincing me as a BA. The arms, yes - but the rest of it looks more like a light 'Mech, somehow, than a BA.
Hard to say why, but a BA should look like stuff strapped around a human figure, or a casing into which a human fits. This looks too - "organic" has the wrong connotations, it's not about biology, but it all fits together as a thing, not as a thing around another thing.
(And yes, some canon BA piss me off royally!) But look at the Elemental, or the IS Standard - they're definitely bulky suits on top of a human, to my eye.
Maybe make it clunkier?
