Agreeing with others - bad reference photo. Ditch the myspace angle.
To get an accurate opinion, you need to provide an accurate picture. Something plain, eye level, shows whole face, no crazy lighting / contrast.
Going off what is there, my initial impression is that your hair looks a little dry. You're going to need to look after it well if you don't want that dye job causing major split ends.
(Heh... sorry - I think I just gay'd all over your thread

).
From what I can see, I don't think it makes you look more masculine - but that said I really can't see much. You've set up the angle, lighting and cropped in a regulation myspace manner, making it difficult to tell what your actual appearance is.
