Did you resize the sheet at any point? Doing that usually creates anti-aliasing that makes the image blurrier, which tends to ruin sprites.
Just a sec, it could've been your image hosting site that resized the picture; Photobucket seems to do that sometimes. Maybe someone knows a site that doesn't resize larger images?
