Wow!!! Bloody Brilliant! well done to all involved! I really enjoyed it and loved the sets, scenery and special effects, really professional results, almost a glimpse of what an ALIEN remake (god forbid the hollywood machine ever touch it) could look like. Looks like you had a lot of fun doing it.
Just a few comments, not criticism in any way:
Great choice of Ripley....good cheekbones! although she does get that space suit on pretty fast, a bit more fumbling with the helmet seal might have implied that there were some inner workings fitting into place before we hear the 'pffft' of it sealing.
Love the Xenomorph, although I think it would have been far more menacing without the bambi eyes. How could she blow it out into space? It was cute and only wanted a hug

I think the soundtrack could be tweaked a little to add to the tension of the moment.
I liked the yawn from Ripley, the teddy and the wink from Jonesy........these all implied a little tongue in cheek fun and a playful nod.
All in all, it's a really great piece of work. Thanks for sharing.
