Oh my.
Quality wise, this is one of the best first songs i've ever heard. That kick is punchy as hell, the snare fits nicely with it, great (albeit fairly loud) bass, and a nice saw lead over it.
Here's some criticism though. On all your transitions you used the fruity Free Filter. You might wanna step away from that; It's a really full on effect and needs to be used sparingly. I recommend using reverse crashes, snare rolls, and other filtering effects for your transitions to keep things fresh. There's alot of things you can do.
Also, I think some of your instruments are a bit loud. The bass kind of drowns everything out, along with your saw lead. You can barely hear the hi-hats over it. Try working on that next time :P EQing helps alot too. By cutting out frequencies you can make room for other sounds while still keeping the same volume.
1:22 was an awesome break. Some effects here and there would do awesomely. Maybe some delay on the piano? That lead you had over it was a great call too by the way, i'm a sucker for distorted, airy type things lol. Only problem is your transition back, Maybe try filtering your bass back into the song at 1:43? As is it's kind of ... jarring :P
There's some other stuff too, but since this is your first song, i'll let it slide :P Seriously awesome work here though, Some people take ages to get this good of sound quality. Song structure wasn't that bad either, reminded me of a few of my first songs; Dancey bass, Catchy lead, and of course a piano break lol.
... Whoa, sorry for the wall of text lol. Anyways I look forward to more! Keep up the good work dude.
