Photo retouching a portrait or fashion shot. If you need a portrait to have punch and depth its a good idea to clean up any distracting highlights or shadows to keep the focus on the centre of interest. Add some depth of field to give a long lens look which also emphasizes the main focal point. Most fashion is shot with a long lens to compress the facial features which gives a more flattering look. Wide angle lenses tend to emphasize noses and other unwanted protrusions. Once the main clean up is done the retouching the portrait can be carried out, smoothing skin and tone and shaping if need be. The final stage would be adding the drama to the shot by creating and HDR look or high contrast black and white or other proven technique.
My take on an HDR style portrait and portrait retouch. Many thanks to Kenzins1977 for the image.

Portrait retouching with drama and depth of field
Notes: Portrait Retouched. Skin retouched, reshaped nose and brightened eyes, lightened face, darkened image, made HDR style, dodged and burned to enhance the drama, added depth of field to simulate a longer lens.
