To start with a nice little vig. I feel that the Snot should come the oposite way around to make it look smoother. I think an explosion would be good added in. There are many ways to make explosions: You can use bionicle trans orange round balls or you could connect flames together in the gaps. The photos are a bit blurred, but, I can understand if you have a bad camera. Here are ways you can make it better though: Put on the Flower (MAcro) on your camera. It is great for close ups. You can also use a tripod (I don't but, it is a good thing to use)

Overall I like how the scene is set up but as has been stated the blurry pics distract from the overall presentation, also I'd suggest maybe adding some lighting fixtures or even a blast hole in a wall to show where the aliens are coming from. Love the alien craft in the background, adds to the feel of the whole look. Also as has been stated before, try adding more scenes if this is going to be a storyline so it is more interesting, and add dialogue I'd say.
The experience I got from stories is that the scene should cover the whole screen, the only background should be the sky, if it already has to be (nobody is pressuring you into buying tons of light blue after all). Also, every episode should be its own story with action and story and possibly multiple scenes, it makes people want to see more of what you are making and you get loyal viewers, which allow you to experiment in new themes without the fear of being forgotten in the transition.
Blurry pics kill a presentation. They tell your audience that you don't think it was worth taking the time to get a good photo. Specifically, the photos of the characters are really blurry. The alien ship is a nice touch. The facial expressions of the characters are slightly odd. The old guy getting eaten has the right face, but the young guy seems sort of board by the whole affair, and the female seems smug. Odd emotions for this particular scene. Stronger lighting and focused pictures would help this MOC greatly. Attack!
Very Nice! Like Space Gypsy said, the stealth ship is a very good idea. However, the blood on the amputated arm is a little over done. Unless your going for a Dead Space affect. And next time, (this is optional) use a tripod so that most of the pics don't come out blurry. Other than that, it's great :)
