Nicely done, brings my eye to focus right where you wanted. Try some other lighting techniques for more dramatic results. Subject matter may have people re-doing the puzzle rather than commenting on your photo. I like it.
Not what I would typically think of as stationery but you do write on it. I really don't have any suggestions for improvement excpet for removing the small area at the upper right hand corner which isn't part of the crossword puzzle and not part of the black background. Maybe a little more contrast or converting this to B&W would make it pop more.
