I think it looks better a little crooked, because it makes him line up better, because he was sitting more to one side, so instead of the stairs being straight he is.
ah ok cool i think that's the way i had orignially taken the picture, with the stairs straight but he was crooked. then i cropped it to where he was straight but the stairs were crooked. then i left it alone for a week and couldn't remember where i was going with it XD

You're photography style is really close to mine, if I had a good quality camera, at least.
