It's a little harsh and the base could be lass less repetitive (though it' very catchy). The melodies are good and the central part of the song is really good. I think it would benefit the from having the high pitched sounds being less harsh.
Another great DnB song, keep up the good work! :D Though there's one thing I can't ignore, you seem to use the same ending a lot (adding crash to the drums and fading out). Though it's a nice ending, I think you should start trying to mix it up a bit.
