Now essentially all good - I like your backgrounds!
Try and make the mission a little harder - I can play sitting duck in the entire mission and yet still win . . . perhaps make the Herc wing focus on the player? Or you could increase the AI stats of the drones.
With the bonus objective scan, you might want to change the message to "Drones eh? I'll inform Command about this . . ." so the player realizes what they are - not like they have some hidden treasure.
Also, the Primary Objective "Destroy the Apos" contradicts the briefing capture instructions. Just needs a bit of clarifying.
Finally, there is no bullet information for your bonus objective. I just downloaded the latest copy, so I guess you forgot to change it.
Good job so far.
