It does not lack anything.  It a good photo.  Getting comments is not just about a good photo, there are many factors, timing of when you post to maximize the amount of viewings.  Look at what's around at the time see what others are commenting on.  Also you have to make comments on other members work to get comments.  I don't get many comments, but there again I don't make many.  As a Moderator I don't get much time.
