Hmm... you haven't submitted in a while.
You need to keep submitting regardless of anything if you want to get anywhere on NG, you know... assuming you've been consistently making music since the last time you've submitted, and at the same rate at which you submit, I really can't give accurate advice. Still, I'll give you advice for this song. =)
It starts out very nicely, with good atmosphere... you could change things up a bit sooner, though. That high-pitched, echoing synth you introduce later doesn't fit at all, though, and gives me a headache. You introduce percussion at a good time, though it doesn't change often. The synth you introduce after percussion, while it brings a good harmony, isn't a good choice and doesn't contribute to the attitude of the song. Something else I noticed is that you don't give anyone any reason to keep listening to the song... true, parts of it are catchy, but you change little and some parts are a bit annoying. Worstly, there's no ending - what's a song without one?
You're very good with harmonies and atmospheres, it seems, but have trouble using them and keeping consistent with them. It seems you also find melodies and percussion and having diversity difficult. You have trouble choosing the right synths/sounds/percussion instruments/etc. Work on these weak points and you'll be well on your way to making a decent song.
One other tip for you is for you to try listening to some more professional techno more often, even if it just means listening to more famous artists in the portal. It'll help some. =) Hope to hear more from you sometime... go ahead and PM me if you want a review later on. =)
