Have you been playing NWN for 8 years and wondering where the elementals from your D&D games went?
They've been found!
Well, they've been created. :)
This package overrides the appearances BioWare's basic air, earth, fire, and water elementals with ones that look much more like how I imagine elementals should appear.
Air: Working off BigfootNZ's superb Air Grue (link), I removed the debris, removed the third eye, changed the eye color, and lightened the smoke color to look more like light fog. No longer looks like some sort of genie.
Earth: This fellow lost the "hot" emitters, gained a brand new skinmesh of earth (dirt), and picked up a few small extra rocks and some glowing green eyes. He's much more solid now, instead of a pile of levitating rocks.
Fire: An alteration of the air elemental, this one glows bright orange, with red eyes. I also removed the "whirlwind" run/walk animation. Gone is the pot-bellied magma guy.
Water: No longer some sort jet-powered genie, this elemental is a living wave, with glowing blue eyes and a larger wave-shaped skinmeshed body. He likes to splash water around when crushing his enemies.
Two download options available: override and hak.
Edit: Seems I forgot a minor texture file with the initial upload. Now corrected.
