The visual state of gas giants since the oceans were added seem weird. They feel way too much like giant ocean worlds rather than gas giants.
The atmosphere should probably be more cloudy, and the ocean surface should be more like heavy clouds than just water surface. Light from the star should probably also become dimmer the closer you get to the ocean surface, so it doesn't just become suddenly dark because under water.
Maybe it would also be interesting to lower the ocean surface level more too, but that might not be very backward compatible.
