Arsians_com Hey man, thanks for the in depth response. Glad my feedback was taken in good spirit.
I don't get what you mean about tilting not being possible in passthrough. PT and VR are exactly the same aside from one having the background removed (and subtle differences in scaling and perspective due to the nature of the tech). Film it the same! If you look at SLR's PT videos you'll see no huge difference in how they shoot except for PT is more demanding in terms of precision, hands, etc. Some positions work better in PT / VR but essentially it's the same concept.
I understand you don't want to confuse the viewer by having the action outside of the default view when looking straight ahead. In your BJ scene, you can have the model start by standing then dropping into position, so the viewer understands they should look down. I think everyone starts watching a scene looking straight ahead, so ideally the camera angle should mimic that - I look down from there to see my virtual cock.
This topic starts to get pretty complex honestly and we could go back and forth too much. All I will say is you don't need to overthink the "rules" of PT. We've got enough scenes out there that we kind of know what works and what doesn't, and tilting is definitely a thing which works fine for certain positions.
If you could film exactly like recent SLR passthrough examples that would be fine for most of us, I think! Obviously bring your own creative aspect but start by following the work that others have already done.
BTW I forgot to mention, you also have to watch your vertical alignment. Check the vertical levels of the left and right images and they are slightly off (left image is lower than the right).Even a small disparity can break the scene or at least give the viewer a headache. Something to quickly check in the edit.
