One thing I think needs to change artistically at Starfleet Academy is the Commandant. The Comandant of the Academy needs to be at least a Rear Admiral Lower Half. As it is now, he only has a commander's pips. In TNG, when Admiral Gregory Quin wanted to promote Picard to Admiral and have him take over as Commandant of the Academy, he made it sound like being an Admiral was a prerequisite for the position. And we were later introduce to Admiral Brand, who was the Commandant. I'd redo his uniform as such: SFA uniform. Red (A6) torso and pants stripe. Black shoulders. Gold (C12) dividing stripe. All Good Things combadge with gold backgroung geometry and silver delta symbol. Gold Rear-admiral's rank insignia.
It shouldn't be that difficult a change. Not only would it grant the NPC an appearance of greater authority with the rank increase, but the different color style of the uniform, closely resembling a TNG officer's uniform rather than a Cadet or instructor's uniform would make him stand out as unique.
I personally want a Star Trek game that is actually Star Trek. On a qualitative level that could be a lot of different things for a lot of different people. But on a quantitative level, if the developers were to watch star trek and make the game like what they see, then at least it will be a shot in the right direction, as far as I am concerned.
