Very nice image. The focus is crisp on the main subject of the composition. The composition is interesting, the addition of the pen keeping it from feeling too empty and leading the viewer's eyes to the important part of the image.
This image has a nice feel to it, I like the lighting which shows up the texture on the diary very well.I also like how you`ve composed it with the words in the middle of the image but at an angle to give it that little bit of interest.The focus seems a little soft on the pen, but that aside it`s an excellent piece of work.
