Not necessarily cancelled, maybe rather postponed :) Genclops' review is very good in the context, he doesn't know the intended purpose of the theme yet interpreted it perfectly. That's a good review for you!
Your comments on this made me think of a quote I read the other day. I don't think it applies to you perfectly (because I think you do compose because you love it and not for fame), but maybe you're forgetting the joy of creation for the purpose of creation itself:
'Have you ever thought about it? We want to be famous as a writer, as a poet, as a painter, as a politician, as a singer, or what you will. Why? Because we really love what we are doing. If you loved to sing, or to paint, or to write poems, if you really loved it you would not be concerned with whether you are famous or not. To want to be famous is tawdry, trivial, stupid, it has no meaning; but, because we love what we are doing, we want to enrich ourselves with fame. Our present education is rotten because it teaches us to love success and not what we are doing. The result has become more important than the action.You know, it is good to hide your brilliance under a bushel, to be anonymous, to love what you are doing and not to show off. It is good to be kind without a name. That does not make you famous, it does not cause your photograph to appear in the newspapers. Politicians do not come to your door. You are just a creative human being living anonymously, and in that there is richness and great beauty.'
