The colours are perfect! Alluring and pleasant.
What I like the most is that we see the book from it's cover - the unknown person let us see the book- but only from the cover of it. It hides a message to us regarding ourselves and the way we look on others - regarding ourselves - we might hold the book that is our identity and we might think we know who we are just perfectly, but what we SHOULD know is that it's only the cover, the things we can see at the moment. If we work on it- we can get to deeper, surprising and richer layers in ourselves "when the waves grow stronger, the stronger is revealed" - the stronger parts in ourselves.
When we look upon others - we might see just the hands, and they may look crude, we may look a little more and see the book the person holds and think that we get him, that we understand him, but it's only artificial, it's the cover and no more, there is a lot more to find about each individual if we try hard enough and move though tougher situations in life with him. The red warm color concentrated on the book delivers the feeling of worthiness in each person perfectly, in my eyes.

Thanks for a really outstanding picture velimir!
