Thanks for sharing. That's some impressive work!
Some of it reminiscent of SIL; some of it the Borg Queen; a bit of the female Cenobite from Hellraiser; there's some ideas there that remind me of Nastassja Kinski transforming into the panther in Cat People; and of course, I can see a lot of the more obvious H R Giger influences from his Necronomicon book.
It's a shame you didn't include a bit of narration to explain some of your concepts.
Eventually it's going to happen that there will be a hard reboot of the movies' storyline and I think your ideas are very inspiring for such a thing.
