too much. learn about normalisation and head room. the piano samples sound nice, but you need a bright piano to compete with that resonating bass (which is way too low on the db scale dude, be careful because you cant hear sub bass, and it makes you go deaf)
3:15 is what this song should be, a nice acid bass to accompany the grand without having to compete. nice percussion there as well.
around 4:00 i liked it alot until you brought the piano back. the key change does not harmonize very well, if you want that experimental style break you need to break the entire track down, then buildup to your next part, like the "traditional" dubstep routine.
this is a great first try, but at 5:45 i was done with it. dubstep is fun to make, i make some too, but if youre starting out try and find *your* sound, something to separate you from everyone else. when you make dubstep youre making a style of music where people are highly critical and would usually prefer their favorite few producers. i personally dont have much faith in the genre any more.
but make like half a dozen more tracks, and dont take breaks while making each one. dont plan on uploading them and just have fun.
im just a nobody whos been doing this for a few years, and its really difficult work. a lot of it is common sense. sure theres plenty of kids on youtube who spamalot and have cookie cutter pop EDM, who do get thousands of views. But over the many who ive listened to, i can only remember a couple because they had a unique sound.
so, in a market full of kids who pirated a copy of fruity loops and some vsts, we all have to be that diamond in the shit.
