Right = The song has a pretty catchy feeling to it. While it does have it's flaws, there's times where the song can take off in places. It's better than most Trance songs releasing lately on NGs, so you should honestly be proud of that.
Wrong = You progressed/mastered the song a little weird. First off, you did the right thing at the start, the mono synth and the beat were good, but what should follow probably 16 or 32 bars after the very intro should just be the addition of the acid bass. If you need an example, my song Wicked my come to of some help. All you would really need to do is keep on adding and adding to that first beat, keep it consistent, and then hit the break that would go into the melody. This is all of course if you're trying to make a Progressive/Melodic Trance.
You could use a little more diverse synths. The main synth was a bit overused and lacks the quality of a professional sound,I guess I should say it should be a more crisp synth, so those notes can be better acknowledged. It's also got to be a bit catchy along the way before the melody, which you seem to of distributed a pretty catchy beginning.
I really can't help much here. I just don't know what kind of Trance your trying to master here. At times it does remind me of Progressive, but then at other times it comes across as Club/GOA.
Anyways, what do I know >.<
