1.use Healing tool (together with clone tool).. good to removing pimples or hole on the face. Alt click any part of the face. to clone the colour. then just click click the rest of the part.

2. If u use clone tools, make sure u use airbrush (soft edge) instead of hard. difficult to explain. that you have to experience by urself.

3. make it fairer.. you have to select the face..(exclude those mouth eyes etc) then adjust with either Levels, or Hue.

4. Make your face thinner.. eyes bigger or make nose like michael jackson. Try using Liquify!! Very fun
