I get this darkness stuff all the time so don't be too worried over it. Evidently you and I both have our monitor setup brighter than most so that everything looks good (to us) but others can't see. What I do to fix that is to put a solid layer of white over top of everything, reduce the opacity to 50% or so, then set the blending mode to soft light. In the end it's much easier for me to do that than to tell everyone that their monitors are too dark Keep up the good work.
