I just wanted to add this one. I liked the way your final one turned out except that I didn't like the shadows. Probly they don't have it in PS7 but one of my most favourite tools in CS is Shadows - Highlights. I have mine preset to how I prefer it and mostly it doesn't need any more adjustment. With this one I did give it a bit more light in the shadows but it only takes a second. I'd hate to lose that tool.
My first time of emailing to this blog. So hope it works and that you like it. I know that was not the object of the exercise and so you might have fixed the shadows anyhow if you'd had more time.
