Very good scene, some innovative ideas wrt transitions and overall scene-control. Animations and transitions are not :quite: Vamurai-level, but definitely upper-league.
A particularly welcome addition are the well-realized reset-option and some granular gfx control options. Other than in TGC's scenes, I haven't seen much comparable. I can only hope this will become standard with scene creators.
There are some minor "rough edges" wrt default VR-viewport positioning & Embody activation - but most of VaM's VR users should be experienced enough to easily adjust everything to their liking (If you find yourself in a perspective you didn't want - toggling Editmode will deactivate Embody, as per usual default setting).
My only regret is that I'm not a really good fit for the target audience of the paid version. Other than that, a well-earned five stars!
1) Having 20 dependencies is standard for a scene of this magnitude: I can assure you that I'm very careful with that (as you already know :P) and every single one is necessary and really worth having in your library!
2) You've got a lot of options to change the lighting directly within the scene if you're not happy with it: initial setup, multiple light switches & FPS Manager to improve/reduce lighting quality.
3 & 4) It's very likely caused by the fifth point: changing the models. Penis misalignment can sometimes happen but should fix itself quickly; I was worried it could be caused by impersonation in VR as it may influence the hand positioning: it should not happen in 3rd person view.
5) Changing models will break alignment in any scene if the new models aren't *really* close to the original ones.
Try it for a bit longer without changing the models, preferably in 3rd person view :)
