I think he looks awesome. I do think you should play a Fighter's Guild guy--the mayor won't see much action and would probably do better if he was an NPC nobody in particular played. Plus Fighter's Guild guys get more fighty explosive funtimes.
Since he's got a sword and a shield there that should prolly be his area of combat expertise. Maybe he's firm on the stance that traditional weapons are awesome and more reliable than more exotic weapons like flails and stuff.
He could be a noble ex-soldier, but with the setback of greed out of necessity; maybe he really, really needs a large amount of money to pay off a huge loan, or afford some weapon that was an old and precious heirloom that had been in his family for generations until it had been stolen, and he's come to Skuldhellir hoping to make it big so he can do that and then leave. He probably wouldn't have any loyalties to the town to start with 'cause of that, but they could very well grow over Time!
