These are all SO COOL. You are very giving to the "community at large" and it is appreciated.
I have found _most_ of these models (for XNALara XPS), but some are just hard-to-find (might find a link, then it's a dead link)... one in particular is a particular armor on the Asari scientist ("impossibly beautiful blue girl" among friends .. It's not that I want to add to the piles of nasty stuff out there... but I find her unadorned form very beautiful (the "Canon" or "lore" version, with the convincing asari skin... not the silly-looking, almost looks like a tight-fitting blue-burlap bodysuit skin that is everywhere - along with ridiculously oversized.. well- anyway, apologies if this seems distasteful. I'm honestly planning artistic poses, not even erotic at all (unless the unadorned form itself is an automatic qualifier). Don't sweat it though - these reference images are stellar, and very VERY generous of you.
