Very nice looking scenario. I love the four different groups with different missions--so reminiscent of the old computer games.
Limiting Alpha and Beta to four fighters (especially four TIE/ln) might be a bit too restrictive depending on the point level. It's pretty hard to spend 75 points on just four TIE/lns. Capping the Rebel Strike forces to a maximum four fighters makes thematic sense, and even if the point level is set at like 125 it's pretty easy for the Rebels to spend that on four ships, but maybe the Imperial players shouldn't have a cap.
