Well, at first it wasn't "all" playful play. I did something wrong, so I decided to just start over from the beginning. I had done quite a bit after starting over -- without saving the document -- when Photoshop decided to crash on me (which rarely happens).

Oh, and...layer comps...they are a dream! I had heard of them, but didn't know anything about what they can do -- and how awesome they are. I have spend a lot of time turning this eye and that eye on and off, trying to remember what I had done in a document, and what combinations I had liked the best. This will be wonderful!

I actually love these hard mix looks...fun! I love how parts of this one blend into the same-colored background.
