This mission has a great setting - I love the details on the space elevator. It has a very distinct feeling of place, and the encounters all seem very interesting.
The main thing that could be improved is having a specific objective/explanation as for what the players are there to do, unless this is a setting pamphlet. The art is also great, but should probably be more transparent under text to increase the contrast and make it more readable - the large map especially.
Another minor thing would be to move around the locations of the elevator on the first page, so that they match the art on the title section.
