Glad to hear about the Eye.
I'm not planning on modding all the guardians to be symmetrical, but some anyways. I find that asymmetry needs to be striking, like in the guard posts, otherwise it just makes it feel like it's 'accidentally lopsided', so to speak, when it could look orderly instead.
Actually, looking at the original beam guardian, I'm guessing it actually is symmetrical, but viewed from slightly to the side. I wonder if the originals are some sort of 3D fractal art or something. Not that it matters, but would be neat to know.
