I love it even for a remix
I can tell you are pretty much brand new to the electronic music production scene.
This does not fully qualify as dubstep, unfortunately. There is build, but it builds to nothing. No bass drop (whether pure sub, or bro drop) to be found here. I feel a slight sub bass, but it is not really enough.
I also recommend Soundgoodizer if you are going to use a default piano synth, as the sound immediately shows the amateur nature of this piece.
I enjoy your melodies, but nothing really helps save this piece other than that.
I am not trying to hate, but provide some constructive criticism through brutal honesty. You are new to this, and there is nothing wrong with that-- we all started small. If you post your stuff to Newgrounds (which is good that you do), then you need to expect some serious (and some not so serious) feedback. You have LOTS of room for improvement here, so you have nowhere to go but up.
