Adjust her proportions
Master the tones
As the sketch develops, I concentrate on getting the proportions of my character correct. The best way to do this in Photoshop is to create a selection with the Lasso tool and then move the chosen element with the Transformation tools. It’s more efficient and effective to work on small areas at a time, rather than try to correct a large area of anatomy in one go.
Define materials in the scene
I give her a leather jacket because it suits her street look, and because it contrast with other materials in the scene, such as the plastic on her shoulders or rubber on her shoes. When painting textures without references it’s helpful to place two very different materials (matte and shiny, say) alongside each other.
