That's a really neat design!
It's a nice mix of mobility suit and fashion, and really provokes alot of question about the culture that developed it.
It the bottom a sphere that is kinda like a track ball in an old mouse, in the sense it is able to roll and is directed by the frame above it/the is semi free standing?
Also are the more anthro characteristics like a the separate head (nice eyes btw!) and the "hair" allowed/channeled by the mantel/gorget?
Also are those arms tucked behind her back, and do they have hands that are mech or slime, or a bit of both with mech palms and slime fingers?
The mech gauntlets/slime fingers design might allow for some tentacle/whip like motions by allowing the fingers to extend and contract.
Ah, sorry went of for a bit there, like the color scheme with a focus on greys and dark to light blues with the yellow as highlight and the red a central focus, which I know "slime cores" are part of the traditional creature design is some ways, but the way you centered it and related it to the yellow mech pyramid core was neat.
Thank you for making this.
