More minis for Hordes of the Things

At our last Hordes of the Things gameday, we talked about putting on a big battle scenario for HotT--Ragnarok--using larger-than-normal armies for the frost and fire giants. To that end, I purchased a bunch more Heroclix (and one D&D Miniatures figure) to add to my Sons of Muspel:

In addition, I saw some minis that inspired me to start working on a Frost Giant army to compliment my fire giants. I have enough figs here for about 8 AP worth of elements--probably Warbands--one-third of a standard HotT army:

Finally, while these models don't fit a current army, I like the translucent green. They might someday become part of a new force, the spirit of nature army.

Anyone else building new armies, for Hordes of the Things or any other game?
