Nice pictures, its quite nice to work on stories.
Personly I tend to think up the story first, taking into consideration my collection to know what can and can't be done, then I set up the enviroment, and then I spend about a day or two taking pictures here and there with the set up I have.
I dont have the room to keep a set up standing for long, so its always working fast for me. I put everything away after the pictures have been taken.
