Placement

As a lover of Van Gogh, here is another piece of his to illustrate focal point. This piece, I believe titled "Bedroom", has a focal point on the right side of the canvas.  To me, the focus point is the bed, which is disproportionately large in comparison to the other elements in the work.  It is a different color wood than the chairs and the desk in the piece, and it spans nearly half of it's width, meaning to me it has more significance than the other elements.
