This was a really fun tutorial and I learned loads. It was hard though, so not for the faint-hearted.

I didn't follow every step, due to a lack of time. But I'm still pleased with the results. I didn't pay as I did it on skillfeed.com during my 30 day free trial. Sadly (or not, given how sore my eyes are after this Adobe-fest) my free trial is about to end now. Still, plenty of other free tutorials around :D
