Well, special renders should be that, special. I mean there is no reason to keep them lore friendly with the main game. Let your imagination fly, make Isabella in Space and the such. Last one I remember was Isabella-Noir and that was well received here at least, Idk about other sites.
In the same vein special renders shouldn't be vanilla always. You can explore other kinks with them, like exhibitionism or whatever.
About the development pace and the difficulties of this update. Shit happens, many devs start strong but at some point they find themselves with writer's block or some other creative block. The thing is this is a game in progress, not everything has to be perfect from the get go. You can redo things later once you have feedback for it.
