For BElf, I would suggest the Spellbreaker's armour from the TFT campaign screen, Blood Mage armour, Dragonhawk stuff, and probably a white column base from Cityscape doodads. You can also add green crystals from other sources (Ancient Ziggurat hidden texture) and/or vines and flowers from the various nature props.
I second the other suggestions you quoted.

Especially the Death animation one.
