Thanks for your questions! 😄
* I use Blender for the character models, WAN (AI) for the animation, and After Effects for the final editing.
* I've seen a few requests for Xavier, so I've been thinking about it, but I'm still not sure yet.
* I'm not really interested in dildos, so it's probably not something I'll focus on.
* I do keep suggestions in mind for future projects!
