Please don't fall in love with a chandelier to go over your bathtub! It's not only dangerous, but quite possibly does not meet the code requirements unless your bathroom which you say is quite small just happens to have a very high ceiling.

Building codes usually require a space of 8' between the bottom of the chandelier and the top of the tub, plus the chandelier must be rated for wet locations.

The two horizontal fixtures could work well over the sinks, but you might instead consider using 3 vertical fixtures for a more contemporary look, with one between the two sinks and the other two to the left of one sink and right of the other.
