Was that meant to be a pun? I took 'aspirations' to mean Krennic's desire for recognition from the Emperor. But the hand gesture was laughable. It was like he'd just released a little budgie perched on his finger.
What stood out for me was the bacta tank shot followed by Vaders entrance from a misty background, like he just got out the shower. We're the emperors guards there to towel him down?
"Aspirations" as used has a double meaning. One is Krennic's aspirations for recognition and power, as you pointed out, the other being "aspirations" referring to drawing in a breath which Krennic was unable to do in that moment.
