Hi there.
I noticed your studio because of Alexa.
I like seeing someone behind the scenes actually looking for suggestions.
First off, a perfect scene will never exist. You could get tons of suggestions from thousands of viewers and every single one will be different.
Silly-Sausage made a good point about closeness and intimacy. This is imho a key factor of VR, but closeness is a really tricky part. Too close = cross-eye effect, too far is just not close enough.
Yep, image quality matters quite a lot. Like overall hardware and other factors, for example lighting, color balance, distance from performers, etc. For these factors, I'd suggest you wear a headset and watch a ton of videos to understand, like truly understand, scenes from our perspective. Sound quality is important too. Hearing her speak clearly matters, so mic positions and avoiding sudden sounds or noisy environments are crucial. Btw, moans and sounds from male performers are an instant dealbreaker for me. Guys are not the main characters. Girls should be the shining stars.
Actress. Famous or not doesn't matter to me, as long as she's pretty (that's subjective for everyone). What matters more is how well she can understand and play for VR and the scene itself.
For scenes, I personally prefer solo/GG, but for BG scenes, fewer positions is better. Probably other folks will disagree with me, but it could be interesting to have a scene directed around one viewer position. Let's say the male is sitting and the whole scene is about that from start to finish (BJ, CG, RCG, different leaning angles). Same principle for standing/laying. Studios often try to fulfill every angle/position to hit everyone's taste and the whole scene becomes a mess of positions. The result is I skip parts I don't like. For example, if someone is laying on the bed, standing doggy could work but it instantly breaks immersion. Same for someone banging a torso toy in missionary then sudden CG breaks it too, etc. I don't get the ridiculous length of some scenes. From introduction to aftercare it could easily be up to 50 minutes.
For me, the finish is really important. I think everyone loves something different (creampie, CIM, facial, whatever), but what I'm mostly missing is aftercare. I'll cover just creampie and CIM. For creampie, I really hate shallow quick shots and showing proof of "money shot" to the camera, aka almost having that creampied kitty in my face. Ideal scenario is a natural deep shot, staying in position for a while with some aftercare and verbally emphasizing it (that's what works as immersion for me). For BJ/CIM finish, I like something similar. A bad finish is cum in mouth then quickly showing it to the camera while the guy is still pulsing. That's really weird and kinda unfinished. Rather than that, cum could pour out of her mouth around his cock, not those "half finishes." Then some aftercare like cumplay, etc.
Those are the main things I can put together right now.
Take care.
