I love all of your ideas. I was looking at your beefy zealot and thought that idea was very humorous, but cool as well. I think you need to work on your colors a bit, but that's just some constructive criticism if you don't mind. I see allot of hulked out creatures, mechs, and soldiers on here, but I think you've hit the heaviness of it perfectly. Nothing's too overwhelming because of the size of your ideas. I love it all!
I rather like this design very much, it definitely is authentic. What is it's power source? It's armor looks somewhat organic. What are the red lines as well, they remind me of Zone Of Enders?
too much red...
overwhelms the overall impression.
