Way of the Astral Self flavor idea help

So I made a astral self monk as my backup character (custom lineage wood elf, w/ telekinetic feat) but I wanna have his Arms, Visage, Ect., be something more interesting than the book’s descriptions. Wanted to put out some ideas to see what you all think, and have you guys tell me your ideas. (Sidenote: this character was to be based off of the Buddha, but if he just got up and said “Fuck enlightenment” and did a 180 personality / philosophy shift.)

• My first idea was why I took the telekinetic feat, I wanted him to be like Shigeo from mob psycho and have his “Arms” be taking like rocks n’ shit from around him and just smacking people with them. And his “visage”, would just be glowing tattoos or some shit.

-My second idea was to have his “Arms” be him summoning a disproportionate 10ft. Katana and have his “visage” be a tengu mask with a white mane flowing behind it. The idea with this one was that in mythology, Tengu were master swordsmen and generally against Buddhism and this would reflect his abandonment of his teachings in favor of his selfish goals.

If any of you have any other ideas post them in the comments. Also let me know what you think of my ideas here.
