Cool stuff indeed, I would however change the stairs in that one shot, you have a cool railing design and then a cheap stair case that doesn't match the design of the railings.
I quickly did a sketch in max to show what I mean (I didn't do the railings on the stairs, but I would also add the 1 1/2" tube on the stairs in a soft curve same as the base of the stairs.
Here a render of the base:
