You may want to look at the character from a GM's perspective:
The character is smart, educated and has a good selection of skills.
He's a noble, but is there a Terran nobility?
Titles are usually granted by a ruling sovereign in exchange for fealty and service. What gives that title value to merit an Enemy? He isn't landed, with property generating income, so how does he live and who does he want to work for (he has no job until the GM hires him)?
As a GM I ask any player looking to play a noble if they know what "Noblesse Oblige" means. From those who are granted much, much is expected.
Where does he explore? Does he leave Terra? Is exploration a job or a hobby?
He has a selection of combat skills, is he expecting to use them? (With Glass Jaw I strongly recommend avoiding melee)
Before you play any character, look at how a GM would sink his teeth into it. I've had players take on severe mental and emotional problems just for more points to spend, and I give them time to think it over...but having a Trinary Commander with a plant fetish who cried like a little girl when he was upset, made for a fun campaign...for the other players.
