Thank you, that's really amazing feedback! Especially the bit about facial expressions, as that's the most common complaint I get - some people can't read them at all, and think I don't put any effort into it, but I really do! I just prefer a more subtle style instead of the huge, over exaggerated, constantly open mouthed expressions that some other AVNs do.
The past/passed thing is something I always screw up unfortunately, it just doesn't stand out to me as wrong for some reason when I write/proofread, so I really appreciate when people point them out.
As for ideas, mostly it just comes naturally to me I suppose, but I do occasionally get inspiration from people discussing the story and theorycrafting on my discord, so if you want to contribute there you're more than welcome!
