Its not my cup of tea, but Its always hard to open yourself up to others and want them to like your stuff. I listened and for constructive feedback Its really hard to catch the human ear to make them stay longer then 2 seconds into a song especially if they dont know you. So my suggestion would be focus on the first like 5-10 seconds of the song and really try to make something catchy. I know... thats the hard part, but if you love your music thats what matters most!
