First muscular is not that important to us. We're not visual like men are. So right off the bat, you're in the wrong direction. Yes we care that you're decent looking and we'll love it if you're hot, but to us this is secondary and can even be ignored.
Second, being a "nice guy" is a problem, it's not a good thing. Here you're not even moving in the wrong direction, you're regressing.
