Adding visual depth to the clothing
At this point I’m still using the same Soft Round brush with the Opacity and Flow settings as mentioned previously. When detailing, I reduce the brush size slightly. Here I mainly work on making the denim look as authentic as possible, while maintaining a painterly texture to the image as a whole. I also make a new layer for the stitching and apply a Drop Shadow (in the Layer Style dialog) to automatically create a small shadow beneath the stitch line. This makes the fabric and the stitching look more realistic.
