A few things:
1. Welcome to MLR!
Here's our intro thread, go say hi to everyone, especially Kyoga

2. For a first track, this is actually really good! I especially like the drums, very nice and breakbeat-y.
3. In terms of feedback, first and foremost I'd have to say that it'd probably be a good idea to sit down and do some work on sound design, because simply using your own sounds in your tracks as opposed to presets can make a song twice as good, and a more accurate expression of you as a musician, and so on and so forth, blah blah blah

I'd also say that it might be a good idea to work a bit more on fitting the samples into the song, because as it is, they stick out more than any instrument. Maybe look into EQing, because that can usually fix issues like that.
