Gambler can go under ships crewman, kind of goes with the flow and raise TFC to (3) now flesh each out with some skills four or four and flavor ones that are not impacting in the game like Engineer what kind of engineer its a huge area I assume its ships engineer so skills should focus on that.
Again read the Cliches and think about your characters, if your a member of a race you must include that somewhere its a cliche', even if under another Cliche'. And one skill in that should be Klingon or Terran to cover all the things we all know they are as a race. I want the cliches fleshed out with a description that people when they see you will say ahah he is the Disgraced Yet Honorable Klingon Warrior Who Really Knows How to Swing a Batlethe (Born and Raised a Klingon, Klingon Warrior, Shipboard Experience, Won Tournaments with the Batlethe', Disgraced Klingon from a Fallen House, Sticks to Klingon Honor). Just think about your character and what people would know about them that stands out and where you can stick in vital diversity points, again just one needs some sort of training or experience on ships or would know a great deal, but that only needs a minor point. Its a there if you are forced to do it sort of skill.
If something like the above adds flavor to a skill like being great with the Batleth' is already covered under Klingon Warror its free a flavor to the character like Spock might have as character vulcan culture, skilled witht he vulcan lyre the second is assumed also under the first its free.
To be a Klingon a cliche' has to have some sort of Klingon aspect. Lets take another genre we all know Lord of the Rings, a warrior who is an elf would at least have to have Elven Warrior and in the cliche' skills have Raised an Elf among the others.
