Not bad.
Apologies for taking so long to get back to you. I have a lot on right now, and it generally takes me about an hour or so to review a piece.
Alright. This isn't too bad, per se. You have some decent concepts, but they're overshadowed somewhat by unnecessary extensions and a lack of anything particularly catchy.
The beginning is fairly important in a song, many people will skip a song if the beginning isn't interesting enough. Especially with electronic music. You can get away with it in classical, but techno is generally listened to because of it's punchiness.
The beat is far too simple to draw people in. Indeed, it puts you off. Because the beginning is somewhat boring, we expect the rest of the song to be as well. The high... thing is harsh on the ears, pull out some of the higher frequencies, they literally hurt my ears with these headphones - and I'm not even going overly loud. Basically, all parts with that really shrill, tinny sound need to have the higher frequencies pulled out.
You have a good premise with the main tune, however, what you have is a backing tune, not a major one. You need something on top of that to catch the listener's attention. Something punchier, harder. THe contrast will help your piece immeasurably.
The main problem with the tune is that it's a flowing one. Everything is a flowing part, you need something to contrast that, so that it's imphasised. It's a good tune, but it needs something more to actually work properly.
The beat is also too simplistic. Bring in a few more beat structures and layer in a bit more complexity, make us bob our heads to it. What you have right now sounds rounded off. There needs to be a definite punch, or hard sound to it. The beat, in itself, is fine. But, as with all the other parts of the song, it needs an extra little something to properly work.
The middle of the song has a very nice blending of melodies and counter-melodies, but they would work even better if they were contrasted with a harder beat and melody structure and sound.
So essentially. What you have in this song is good. But it's half a song. It has a lot of potential, but you need to spend some time adding in the necessary other half.
Do that and you'll probably end up in the top bunch of artists here.
So remember, punch and power. You need a bit more complexity in the beats, a whole bunch of harder elements and a more definite melody section. This is techno, so make us dance!
Or, failing that, at least make us want to bob our heads in time. :P
Good luck! Krayon.
