The articulation on the balconies will be very nice. A fault I see right now is that the railings are set back from the slab edge, not over the edge as shown in the renderings, so it won't be a sleek and sensuous pure form as originally designed. I hope the glass will be fritted, translucent or even reflective instead of transparent to best express its wavy form.
It will be a nice change from some of the crude and gimmicky balcony designs of the buildings nearby.
