>>96062042I know it's pretty late here but I wanted to chime in. First, great work you're doing. Glad you decided to rebuild the project. Wish I had been around during the weekend to give better input.
Sibella: I think you've got her personality pretty well spelled out. In the proposed reboot material from TS, she took on the role of the leader of the group. In some fanfiction she's a bit sassy as well. Not sure if you can incorporate any of that. You kind of already did with the motherly angle. Perhaps she's a bit assertive at times?
I would not forget her humorous side if you can, which probably includes the occasional pun and love of the Elvira bad vampire trope.
Elsa:
I think she'd be more of a tsundere, but not one to pick fights. Perhaps a bit aloof and off doing her science? I am sure some fans will disagree on this one.
Tanis:
I agree with the innocent angle. Probably struggles with wanting to appear mature. You could make that desire stronger for comedic effect or conflict building, or you could just make it a more subtle background trait. I think she'd be pretty smart, but perhaps also naive. (Don't listen to anyone who says she can't be a legitmate porn/romance option.) Options both good for her youthful age or more grown up version (bustier, and probably hipper, but don't forget the bust).
