Our D20 role playing game has magic based on Skyrim. As such, I needed a Flame Atronach for one of the player characters who has the spell Conjure Flame Atronach. The spell creates a flame atronach that lasts for five rounds and orbits the caster. It throws flame bolts and if its killed before the five rounds expires, it explodes doing 3D6 damage. Fun stuff!
Reaper miniatures makes an excellent flame elemental both in plastic and also in metal. It comes with wings that attach to the back. If you don't glue on the wings, you get a pretty good miniature to represent a Flame Atronach.
By way of proof, just have a look at the Elder Scrolls IV Oblivion version of the Flame Atronach and then compare it to the Reaper Miniature and you will see that its a good proxy model.
Painting was pretty simple too. I just followed this process:
* base coat in white spray
* paint in bright yellow
* wet brush in orange
* heavily dry brush in red
* light dry brush in black over certain areas of the model and paint in black the "clothes" and "face mask" on the model.
Simple!
