I like the new pad, conestation and airlocks (check the textures were, they are reversed). It works just fine :tiphat:!
Just a suggestion: the travel tube entrance is too closed and looks like a box:
Can you show more of the travel tube? It has a nice round mesh. Perhaps you can make the box open above the "travel tube" signals. Also, put some black round area in the back wall were the tube is supposed to go. As it is, it really looks as a teleport

.
Finally, use the artwork here
http://www.space1999.net/eagle/graphics.html for the signals on doors, walls, etc. The original author, Roberto Baldassari, gives permission if credited. I'm using his work for the Main mission interiors.
There are lots of graphics, including a Moonbase destination chart and an embarkation point sign that you should put somewhere.
Interesting graphics from my point of view:
Just some suggestions, keep up the good work, looking good as it is!
