I would like to recommend this book:
Though composition is entirely up to how the artist interprets it, this book is incredible as a starting point for beginners with composition "rules" and general tips on what makes pictures you see in animation, fine arts, and illustration work or not. The book is 400+ pages long with a ton of information. My only problem is that it can get chaotic (it tends to refer to information many chapters before which makes me always rewind back since I tend to forget what was stated) but overall, this book is great.
I believe http://parkablogs.com/ has a review up and he was pretty fond of it too. I recommend this book to everyone.
