Imperial Guard Tau Allies

So a good while back I found a piece by Ukitakumuki on deviant art. It depicts a suit designed to help Imperial Guard soldiers in combat. I decided to make two sample models for a possible future unit for my tau army. In addition I've included an earth caste Tau I made a few months ago.

The paint job isn't finished yet, I just wanted to show off the models. The main aspect of modeling that I did was remove any imperial emblems and use green stuff to customize the one chest piece and the other model's helmet.

Here is a link to the piece that inspired these figures (read the description):
