The plastic wrap filter was very useful for creating the shiny texture of the skin. However, the blurry brushes have been more helpful to emphasize the lights on the skin. My tablet was very useful, as you can see that the image looks as a digital and airbrush drawing. But what made my day bright was the smudge tool which is wonderful to use for smoothening the contours and the textures.
