Personally, I think this is better than the pokemon sex track...

-Everything that plays from 10 seconds to 1:23. You use the advantage of electro, techno, bass and percussion sounds to create a catchy and creative beat.

-Their are intersting buildups here and there which make the track change it's pace.

-Right at 3:14 and even better switch in melodies. This would be Melody B. It ends at 3:40.

Disliked.

-I think you rely on the main melody too much. Techno is suppose to keep your heart pumping throughout the entire thing. For me though, there are spots that feel uncatchy. Also, with techno, you need to keep in mind, if your going to rely on a making a main beat, you need to present it differently with diffrent counter melodies and instruments playing the line, or else it turns into pop more.

-The fade at the end. Techno is known for decrescendoing and crescendoing throughout the entire track, but primarily keep it so the ending is loopable, or that the intensity matches the presentatio of the song. I kinda see the loop, but it goes too quiet.

Nitpicking....

-{I would like to see flashier ending}
In electronic music, the endings never give me those moments where the blood flows through my face. Personally, I would like you to study the sounds of other techno, and orchestra (brass, strings, woodwinds, and percussion ensembles) To see the do's and don'ts for sounds. I mentioned orchestra, mostly because the variety of instruments themselves can create such a range of different sound and melodies individually, that it's easier to create hot-spots in music that are just unforgettable.

Overall, good job

REMEMBER, people will remember the first, last, highest, lowest, loudest, and softest part of a song. Make them memorable, even if working on techno.
