Oh how I envy you

Photoshop is very, very time consuming when you have had no experience with it whatsoever.  It has taken a great deal of time to get my image to this:

How I envy those with Photoshop experience right now.  Of course, the more I am using it the better I am getting at remembering short cuts etc.  It took a while to work out how to inverse the picture so that I could delete the background and not the focus of the image but I will never forget how to do this now!
