I took a look at tha Google Doc and felt quite overwhealmed, and I have been playing RPG since about 20 jears ;-)
While the idea is good, I think you are taking it a bit too far, at least in my opinion.
I admire the thorough research and work you put into you own character, and a lot of new players could take a look at that sheet and find ideas for themselves. But mainly, we are here to have fun. Not do write an essay on a fictional character.
Of course there are more things that define your inGame "life" and Character than only the pure biological stuff like age, gender, hair colour ect, and taking time to think about that is important. What is your characters background, what are his desires, his secrets.
What does he want to achieve, and what is the motivation fueling him to rise above the normal mass of NPC pilots clogging along the lanes.
Keep it simple though, for after all you will have to remember it all.
And most players you "meet" will just be sitting in a sifferent ship.
If you intend to write some forum RP, there is plenty of space to fill in the blanks in your character, but it would be rare indeed that you need a character sheet for it. You would neet a set of defined motivations, problems and other issues though, to know how you would react to different persons and situations.
RP is a game of "what if" ...
What if this man threatens me... is he an enemy, or just greedy, or has he a valid reason and I might even offer him help if he where not so agressive.
What if I threatened him ?
What if I where unsure how to react, and had no time to think about it ?
Probably I would use that other defined set of "rules and reactions" I normally use, reacting as the Player, the human I am, and not as my Character ?
I would let my boredom, or my anger, or my greed for credits to purchase that other great Capship with my other account define my reactions. And not the role I am just currently playing.
