Final adjustments

On a new layer, I use my Angled and Round pencil brushes for touch-ups, colour picking from within my image with the Eyedropper tool set to sample All Layers. To patch larger areas, I use the Clone Stamp tool (set to sample Current & Below) to preserve the textures that I’ve built up. A Levels Adjustment layer (to make sure my image isn’t too dark and muddy) tops it all off.
