OK. We need to see a picture of you riding the bike, profile side of course. Lean it against a wall, ride it, whatever. Have someone take a clear and level picture. Only after we see this can we say, yeah, it is too big or whatever. If you are comfortable on it, that is all that matters. Me? I should probably be on a 56 for all of my bikes, but none of them are a 56. I hate the feel and look of myself on a small frame because I have a disproportionately long torso for my height.

tl;dr - post a picture of you on the bike.
