The whole drawing basic shapes thing that people do is what I do for every picture. I just draw the shapes really fast and go from there. If you try to be too patient when you are getting the layout sketched you will over analyze. Try to get the larger picture sketched on and then fill in the blanks!

I never thought of it like that before I'll definitely give that a try in the next few days and see where it goes from there. Thanks for the tip!
