Photoshop Retouching

At a Christmas party on Saturday I met up with a guy who has a photo studio in Surrey and mentioned I did a shoot with a friend of mine in Squamish. He asked me to send up some of the pictures, original and retouched.... anyway, I'd seen this Photoshop Retouching link a few days ago and it's got particular relevance in looking at just what crazy stuff you can do to change how a "normal" person looks into the typical "model" person.
