you used some interesting brushes...did you use light yellow or white to brighten things up? it looks like yellow...what kind of blend mode? I saw you messing around with it a couple times. I haven't used it enough...maybe overlay?
Sorry for the late response. When you double click on a layer you have the layer style window that show up. By default the blend clipped layer as group and transparency shapes layer are checked. You need to unchecked them if you want to use the color dodge layer
