Hmmm... I am sitting here, wondering what doesn't click for me with your release...
I think you were going for that JOI/POV clip experience, but personally I don't think it works that well in VN format.
When you watch porn, there is a lot of stuff happening in "the background" - mostly voice and intonation, but also subtle movements and face expressions.
I feel like posers... aren't exactly best suited for that sort of detailed work, especially when you don't have much experience with them. And of course there's an issue with lack of sound - there was this old trick I read a long time ago, that said if you are afraid when watching a horror movie, try muting the sound - SFX, but also music, have a very large role in telling our brains about the mood of the scene. That's something that could be taken into consideration - it doesn't mean that you have to have sounds, it just means that you will have to work that much harder on your script to convey the mood. Something I will go back to in a second.
Secondly, I would take a look at the medium and try to utilize its strengths - the biggest one being, software can be interactive.
Personally, I think that what TeaseAI and Virtual Succubus are trying to accomplish is the proper way to go when it comes to POV femdom experience - but I do understand that for a new dev, it could be difficult to code a simulated intelligence program that takes into account a lot of variables, remembers your data and gives you that virtual Domme experience in a believable manner. What you could do, however, is to give your players some basic way to interact with the script - e.g., the moment she asks about whether you like feet that are dirty. You could write it in a way that gives the player a choice there, saves their preference in a variable, and then, in a follow-up session, it influences the scene.
Third point is the script, and there are two issues I have here.
One is that... Her monologue does not feel very natural. It's better than the usual ESL F95 shlock, but by choosing to go the pure monologue route, you are drawing a lot of attention to what she is saying, and - more importantly - how she is saying it. In other words, your script pretty much carries the entire experience, so if it's lacking, you have nothing else to compensate for that.
And the second one is that I find the disjointed scenes a little jarring.
I don't know if you've ever been to a therapy session, but a lot of it is about building a rapport with your therapist, almost like creating a relationship with them - which I believe is the reason why dating your patients is seen as unethical, but that's a different discussion. My point is, reading your scenes, I don't feel like I am visiting as the same person - I feel like I could play those scenes in any order, and I wouldn't notice much difference, which I find to be an issue. I think that it could work better if you made it into a progression, where you start as complete strangers, and as you continue through the sessions, she begins to feel like someone you know and can trust.
Plus, I also think that instead of going from 1 to a 6/10 within the first 30 seconds, a subtle escalation would be better - start by having her just talk to you in a completely professional manner, and as she starts to get the hints that you are a sub, she subtly begins to insert her own suggestions, almost in a predatory manner, trying to mould you into her pet.
Those would be my quick thoughts on it. Nevertheless, GL with your future releases.
