My suggestion to you is listen to a lot of electronic music in the same genre as the music you want to make, and really pay attention to the structure of the song as a whole. Try to emulate that same structure in your music. Figure out where the intro ends, the first verse starts, the bridge, the chorus, etc. Just because it doesn't have lyrics doesn't mean these thing's don't exist. Pay attention to what makes each part different. Try out everything.
Your compositions are pretty good, you just need to work on your structure, because right now it makes no sense =] You have a build-ups that lead nowhere, and the whole piece is kind of confusing, but I see a lot of potential in your skill. Keep practicing!
you get a 6 for it being your first try. its really not all that good. not being a d-bag, but compared to the other stuff I have heard today, you hazve a lot to work on. good luck tho, ill fav you. let me know when you put some more stuff up
