Their decent tags only thing really is they all have lighting/brightness issues. If you were aiming for it to be bright and are aware then its find. #2 could do with some better flow and depth though.
Go to the layers you added the lighting/made brighter lower opacity or take out a soft brush low opacity and change. also try levels & curves not just curves.
I've tried them all the time, same result. Black brushing, same result. And most ofthe tiime they get brighter agfter i do some stuff with applying images.
