Here's the image I was working on.. I also posted a close-up so you can see better the section of the face I was trying to do.  Some of it looks out of line because I wasn't sure how to save it as a jpeg and when I moved it to photoshop it messed up a bit.

I probably spent a total of 2.5 to 3 hours on it... It's definitely not as easy as it looks!  But it helped me to form my own procedure of working on it.. Next thing I want to do is look more into using gradients to blend the different sections better.

I took a few images and thought one of these two would be best.. Obviously, the background will be different.
