More sex driven? do you feel like the model lacks NSFW content?... or you mean more fetish oriented? I'm more interested in precision with the positioning of tattoos and piercings, also a way to make lamias more consistent, for those things merging a model sounds nice, an improvement over the current model, although without being able to extract the tattoos or piercings by means of differentiation between images to automate things, that, may be to huge of a manual task and a waste of time in terms of what is doable right now.
For niche scenes... haven't tried it yet but aren't those doable? the handcuffs aren't I already found out, but haven't tried torture and such things yet.
