First song, we've all been there.

Ok brosif Here's a review for ya :)

You've already mentioned that you're aware that your samples need to be changed.

Your kick just doesn't have that "kick" that it should for drum and bass. You get that from layering kicks. Your snare should be loud and sharp like a glock going off next to your head. I hear what you're trying to do. Don't use FLstudio's little step sequencer it's terrible. If you want to get those awesome sounds you need to cut up wav samples. Start with an amen break if you have to to get the feel for it. Check out my tutorial on youtube :) It'll give you an idea of how to get going :D

oh i see

i like it but at some times it sounds a little plain but im giving you 5*'s anyways just so other people can hear it...imo its not too bad but its your first song and i see a lot of roise with you :D
