HANDS

It's interesting that you mention 'picture'. People have asked me how I write my work. I've usually told them that a phrase or two will pop into my head and I take it from there. However, lately I've come to realize that I do my best writing when I have an image in my mind. Often it's some abstract notion, and if I write TO the picture, coming up with metaphors that describe it, the result seems to be better. The other thing I'm discovering is that often if I just free-associate to the image for a few minutes, something gets jogged loose. Maybe some similar technique will work for you.
