:) You have a good voice. A good sense of pitch. I enjoyed listening wish the song was longer.
Constructive advice? I almost hate to bring this up, there has been too much debate about this but it sounds as if too much air is passing through your nose on the higher parts. By lifting the soft palet it will keep the sound coming out of your mouth instead of it escaping through the nose. A test for this is to pinch your nose when you sing if the sound is blocked off then you need to lift the soft palet more. N and M need the nose so don't judge on words that have those consonants.(and I may be influenced by all the discussion about this around the forum )
I really enjoyed listening to your song and I hope you post more.
