Hey, I don't like seeing this...
Hey man, try making music JUST for yourself, then submit it to newgrounds. Don't make a demo, then submit it to newgrounds waiting for advice, if YOU like it, submit it!
Try not to do the demo thing, I think that shows that you are conforming to other peoples taste... go by your own taste. It'll go much smoother.
Unless you just wanna make teasers =P
To the song.
I don't really like thedefault FL loops, btw. The beginning would sound a lot better if you had a staedy groovy bassline in the backround, starting from the beginning. It would sound better, and it would make the song sound fuller.
The build up with the piano is nicely placed, no complaints there. With that dark synth though, I don't think you should have brought it in so slow, you know? Like, you could have faded it in faster, and faded out the piano faster, then brought out the big 4X4 kick, with open hi hats and everything.
Other than the small details, this song is actually very good. I'm sorry if I sound overcritical, I'm just nit picking.
Great work, you are full of potential! Listen to more electronic artists that write this kind of music, take a little bit from each of their styles that you like, and your music will turn out fine.
Keep it up =D Check out my music sometime?
