interesting - I kind of like the layout or crop - good choice to include the wood around the books - it frames it rather nicely. the focus could be much better in my opinion, good title though and certainly meets the challenge :)
The hard lighting (caused from a small light source) has created some unpleasant glare. Overall the image seems a bit soft, I suppose this could be camera shake. If this exposure was longer than 1/100 sec, did you use a tripod and trigger with a remote or timed delay to eliminate camera movement?
Out of focus? Seems a little plain. Maybe avoid the shelf framing.....try a different angle......use more less depth of field........fewer books. Just ideas.......hope this helps.
