Don't use the line tool; use a ruler or something to get a straight line going but with varied texture akin to your character. If he doesn't have polished lines, then neither should your background. I think that might be the key to some sort of synergy between the two.
Even if the board was metal and not wood, it would do to have a bit of texture on it. Pretend the background is a character too and add personality accordingly.
