bisected xenomorph mural / holloway's helmet

Hello all... long time lurker, first time poster. Saw alien as a child and have been hooked by its imagery and power ever since... two observations: 1) if you study the image of the xenomorphish image that is the icon for the trailers section, I believe the argument could be made that it is essentially a bisected human, to the level of the fascia, essentially peeling the skin apart down the center and splitting it open... observe the midsection of the humanoid-like creature and see if you can't imagine a phallus being assembled from the two halves at either side... as far as the facelessness... perhaps a shroud is being pulled up and over its head, or the flesh from the chest/abdomen.... 2) with regards to the person assumed to be holloway in the trailer, experiencing some type of infection/transformation... i recall in an inteview with fassbender about an exchange between holloway and david about david wearing/borrowing someone's equipment to go out of the ship, essentially because david wasn't subject to the atmospheric needs of humans... could this not be david??? do compare david's jaw line from a similar angle in the trailer where he is in the star map room looking childlike with wonder.... and the infected crew member... fassbender has a very distinctive jaw line and dentition.... what would be the implications of an infected android? might explain why three converging jockeys might be interested in him... and finally, does the view of the derelict like ship in the banner for this web site not look like a tarantula (spider) to anyone else?!! any commentary appreciated!!! cheers! ~ blackmetalsmoker~
