Now this... this is nice. A grizzled everyman who just wants to earn his pay for the day and go home, wherever that might be. The backstory really gives a sense of who this character is, the flavor text and the personality sections are short and succinct. No exaggerated frills, no unnecessary details or over-dramaticized sob stories. The only thing I'd suggest is adding a bit information as to the origin of this character, i.e. what planet he was born on, which city, etc.
