Sad melody Not a bad try
I like the melody you have going for it, and your use of accompanying instruments; but it sounds like your melody goes a bit odd from 0:13 onwards, it's as if you went from a minor key and tried to go into a major key spontaneously. That's all I'll say for the moment though, because that's all I can pick out. I think that if you plan to expand on this, you should try to have a melody that is consistent in key. I wish you luck in improving this; it sounds good so far, just that little bit at the end I mentioned could be tweaked a bit :)
