I thik that the tip is very small areas at a time. And you can reconstruct the ear with the clone by cloning from parts that are the same colors. You really have to have some imagination on what the ear would have looked like.
Also, with clone, don't forget you can change the brush opacities. Sometimes just a very light opacity is all you need to put a light shadow. Change brush sizes too. Did you see how I reconstructed here?
Have you seen the PSE tut in the ezine?
