If step-by-steps didn't mean adding another hour or two to production time, I'd be all over that. I responded recently to another commentator asking how it's made here:

That link has two links. One leads back to here and the other leads to a post I did recently where I demonstrate some of the process behind a different image I worked on. Certain aspects I like to keep to myself. Some I don't mind giving away. In time I'll probably sit down and put the tricks of the trade on display but I'd like to make a few more before everyone is doing it... LOL
