Haha, I've found this again! You totally inspired me with this back when it came out, and I finally got around to getting it together not too long ago. Great work! Now that I've got some new Tau, trying to think of where/how to plug them into ME as well. XD
Yes, the Tau have some similarites in style with Mass Effect in general, with the clean lines. A cerberus atlas mech perhaps? Maybe but some "horns" on the Tau without helmets and make salarians? Endless possibilites!
Here are some more miniatures (not by me!) to get you inspired: [link] [link]
That... would be awesome!!! I'm looking for some good models to fit, but that proved to be difficult Suits aren't that common, unfortunately. I'm thinking the regimental advisor (dude in the middle), he even has some fitting hair. Maybe even a ninja from infinity as Kai Leng!
