Composition

I am lucky I am very much an ideas person.  I have millions of ideas milling around my head and mostly get them down on paper but not always.  The problem arises with the execution of the ideas.

As a person with no formal art training, I find composition quite difficult.  Is this true with many of you out there?

Also, as a person who has spent most of her life honing technical skills, my work is often too ordered.  I would love to be less restrained but easier said than done.  So today I wrestled with putting a collage together.  Too much, too little.  I don't know I am my own worst critic.
