Based the entirety of this look around the Kaiser Snake weapons in game from the Super Adventure Box. The outfit in use is the Inquest Exosuit. This is my Holosmith character to match with this theme a bit better. I used Shadow Abyss first 2 dye slots, then Electro lemon, and last Creamsicle. This site doesn't recognize the outfit so I cannot post the details here too well on it.
Withe the Exosuit mounts I have majority of them matching my character quite well.
