It's always cool to see how different systems work even if it's from an outsider's perspective (I don't have DID). Depictions of inner spaces, alters, guardians, and so on are really interesting to see in art as it's such a personal thing (even when the alter is from a commercial property).
I hope I didn't miss-use any terms, it's been a while since I hung out in a community that had systems in it, so I might be a bit rusty. Looking forward to seeing more of your art!
