I liked the chord progressions and whatnot, and the builds and drop-offs, but I think the sequence and arp synths (I use FL, too, so I recognize all these instruments) were a tad overused, and lend a slightly "empty" feel to the piece. Also, some parts seemed to lack transitions. That may have been purposeful, but personally, I don't much care for the effect it produces.
Overall, though, I like how it all goes together, and the general flow of it.
Great first attempt. The beats great, and unlike some techno songs, none of the music gets irritating (which is happens a lot to me with these kinds of song) but you seemed to really use all the instruments effectively and in a way to really work well together. I did wish it looped, but that's a small qualm with the overall song. Nice work, and welcome to newgrounds.
Please contact me if you would like to use this in a project. We can discuss the details.
