I've been watching tons of tutorials over the last week on how and why to retouch. I think the perfect teacher would have the following qualities;

Philosophy of Chris Orwig (most definitely a favorite)
breadth of knowledge of Deke McClelland (he's amazingly thorough)
and the voice of Colin Smith (I can listen to him endlessly)

Notes on changing to a Mac.
The magic mouse can be programmed to have a right click. Woot!

There's good...
