1. Skills (Leadership): the only thing I can say to this is, "We'll believe it when we see it."
2. Humanities, Strategy: These are two skills that make assumptions. "His understanding of politics gives him a leg-up when it comes to formal or diplomatic encounters with higher ranking officers and politicians, and puts him in a better place for advancement into leadership fields ... " Those are assumptions. They mean nothing.
The self-confidence he has will be borne out in the RP. So will his ability to be strategic and other things.
Overall: Combined with the history, you're basically angling to have your character become an officer very fast and in a very manly, awesome style.
You try and dilute that point down as best you can, especially on the family member who, as you write, was a "noted ship commander ... and by noted, I mean more of a footnote." But the point is still there. You, or the character, or both are ambitious and want to be respected and important among the setting.
A lot of assumptions I just made there, and I want to know your thoughts on them. Regardless, however, focus on being more of a soldier and less of an officer. Privates have that luxury.
This character is pending.
