I have to agree, Theres a lot of scenery enhancements that need to happen.
Some things I'd suggest.
Limsa Lominsa: Limsa is a sea side grassland on top of rocks. The only way for the grass to populate would be airborne seeds. So there should be plants that look like they are distributing seeds. The air should be filled with a slight pollinated haze Nothing drastic just a subtle bits of pollen and airborne seeds floating about here and there.
Any place where the Sea hits rocks it should crash not "wave about gently" It would only be gentle if it was a lake not the wide ocean.
Definitely add things like whales and large fish floating about when on the boat as well as have the water crash more against the side of the boat.
Ul'dah: lots of things like Vultures, small insects and lizards that fitter about everywhere. Temperate Visual Occurrences. Heat Haze etc.
Gridania: Burn it to the ground and start over.
