The sculpture visually looks too heavy for a glass table. The chandelier is to high and too heavy for a glass table. Lower it and paint it white. The table does not look centered under it.

Get something in blue glass, smaller and rounded for the table. Get the one of these that is 9 inches tall.

These are on Amazon

Your chairs are such a pretty color; I agree that something like tracefloyd posted would look really nice. It would add a little interest without being too much.

I agree that the one piece is a bit too tall and the weight is maybe a bit much for a glass table. Something somewhat smaller may be a better idea because the table isn't really that big to begin with. Just my opinion :-)
