Well, here it is. My first painting…ever? Eye spacing issues aside, I was pleasantly surprised with the result. I mainly used the technique described in this hour-long YouTube video, starting with one base color for the whole image, then painting large swaths of tone over that, then blending using the color picker with a brush at low opacity. Photoshop CS5 actually has brushes that simulate wet paint, but I didn’t use those.
I did use Georgiann’s suggestion of “Brady Bunch squares” by placing a grid over both the photo and my canvas when drawing my initial sketch.
In the video above, the artist makes an observation that really helped me. She used to use tons of layers so she could go back and undo her mistakes, but then she realized that it made a lot more sense to think like an oil painter. “Just paint over it, duh!”

And just for fun, here’s how it looked about halfway through.
