A little bit different from the ordinary but if it works for you more power to you. I don't believe I have ever really heard of Haiku. What can be hard could be that, if you are looking for any commercial success, the balance you seek between what you feel and what will work commercially can be found within yourself. Only you can decide what kind of audience you may be seeking to reach. I myself have tended not to focus on commercialism too much even though I do have the dream of one or more of my writings being successful. Peace.
