For a first attempt this is very good, it was definitely better than my first drum and bass track which was god awful. I love the intro, very sleek and appropriate with introducing the elements to the track.
Here some things which you could possibly work into your future tracks:
.My ears maybe mistaken but those drums sound very similar to the default FL studio drums and though there is nothing wrong with using them it is a good idea to get some other drums to make your tracks more unique so that your not using the same drums as everyone else
.On the subject of drums, add some hi-hats, toms , cymbals to help fill out the higher end of your mix and make the kick and snare feel less lonely : (
Hopefully these were some useful pointers and good luck with your future tracks
