Kind of hard to work on the game before deciding key factors of the game.Seems like a pretty trivial issue if you've still got lots of the game to make. My advice would be just to focus on the more important stuff and figure that stuff out later.
My opinion on that specifically would probably be to not include it all the time, have it there when you think it would be good, but not all the time. Maybe just to get an idea of what he looks like so the player doesn't forget or when you wanna do it for emphasis. Wish you luck.
