Yeah I agree with Thomas, it seems you are breaking away from purely mathematical shapes to more artistic implementations.. I like the white cube with the red shapes inside, that MOI snail model is also really good, would be nice maybe with a dirt-shader to get that old polished silver look on it.
Maybe you should try to get in contact with these guys, I saw some of their products in Milan for the design fair, reminded me of your models a lot:
