Well I like it actually! I don't know how much it would've worked as a creature in the film, but I dig the oniric aspects and it reminds me of some of the surreal Alien 3 concept art, with the baby faced chestbursters or alien sheep things.
The transparent alien should come back. I think with the different layers of skin and levels of the body conveyed through varying amounts of opaqueness it could look really creepy, just add some crab walks and weird body contortions as well.
