I've been doing a lot of 2X lately. Just seems to sort of sink in my mind. I love double exposure type work. It's fun. We tend to approach it differently too-some people just jump right in and sort of randomize it while others more carefully plot out their real estate.
Do you find you want to do more of it? Less of it? Hate it? It's kind of like HDR or Hemmingway's whisky-a little is too much and so much more is never enough!
