My first NG review
Nice sounding piece. I don't think the introduction is too long, especially if you made the song a bit longer ( I know NG has a filesize limit). A few suggestions for what they are worth: I'd put a "classic" 3-step delay on some of the piano and synth parts in the middle section where I assume you are going for a trance-like feel. Also the drum kit sounds a bit default, I'd replace the samples or throw some effects on the drum samples. The ending sounds a bit abrupt but easily remedied. I really enjoy the intro and its simplicity and emptiness and how it builds.
A note about my ratings: I am rating based on other NG songs I have heard, since I don't think it's fair to compare amateur artists, most of whom are still pretty young, to professionals, so a 10 doesn't necessarily mean you are Mozart.
