I like the heavy unit in the center the best. it reminds me of a snapping turtle, especially with the eyes so far apart. I also like its high stance, standing on its "toes" it gives it a maneuverable/spry feel, as if it might be faster on its feet than the heavy-weight build would usually be. I am also a fan of heavy infantry in general haha. great work, all around!
very different, reminds me a bit of Shimmering swords works. hopefuly this will result in more unique armors since everyone else just seems to copy halo.
great job
