First lighting pass layer

I made a new layer and set this one to ‘Overlay’ and also to ‘Clipping Mask’. I placed it above the silhouette but below the sketch layer. This layer is where I add the main lighting details, and as I had already set it to come from the top right it was almost a reverse of the ambient occlusion layer in terms of placement. I used the basic brush and smudged it where needed.
