Teaser is really good, it reminded me of Arrival, the emotion of discovering something new.
The beggining of act one, pages 2 to 6, is less stellar in my opinion. It's basically exposition.
Pages 7 and 8. I didn't get the conversation with the Woman. At the very least it lacked conflict. And the resolution, the "I'm sorry" came out of nowhere.
Page 13. It is disappointed that this series of shots aren't developed more. Instead of the two women standing there talking, they could've been doing something. Like in Lost, the TV show, most of the time the dialogue happened while the characters were trekking through the jungle, or exploring something. It's a missed opportunity.
The ending is excellent, like in your other short.
So, in my opinion, in this script the more the characters do things the more interesting is. The action parts are outstanding, and the setting is very well done described despite the difficulty.
My feedback for this would be to try to hide exposition as much as you can, especially in the first act. One of the films that does this better is Terminator 1 — so there's this scene in the first act when the male protagonist saves the chick from the Terminator, and while they are in a car chase, followed by the bad guy, he explains everything to her, the exposition dump. Now compare this with Inception, which its first act is basically a boring videogame tutorial. Hope this makes sense.
The Trip is better than Vector, in my opinion. Nice work.
