Interesting colour scheme. I like the contrast, but it seems pretty bland for devotees of slaanesh.

As others have observed the execution and skill are clear.

I think there might also be a disconnect between the tanks and troops. On the tanks the tendrils appear to be a livery or paint scheme, but on the infantry it appears to be corruption or mutation snaking across the armor. I'm not sure why the tendrils ate starting on the feet, hoses, and shoulder trim. It why the hoses aren't painted on the back side.

Looks cool but I'm not sold on it.
