Adding Shading to The Masked Denim Jeans

I have my mask made of my denim jeans.

In my layers menu I can see that the blue colour of my jeans is still on the layer below.

I set the blending mode of the Denim Layer to Screen and the Opacity to 50%

Now I select the Brush tool, set the hardness to 0 and the Foreground colour to black.

With my soft brush I begin to paint around the edges of my jeans to add some depth and shadow to them.
