Sounds Sounds Sounds
Hey there. I'm liking the vibe of this track, but i am noticing your sounds are kinda meh. You should really expand your library with some more HQ stuff. You can do good things with some of the default stuff, but if you really want to make some good hits you should upgrade.
Now you're probably like me in the fact that you don't want to really spend money on this. I would recommend checking a site called warbeats.co m. The forums there have some excellent tutorials on things like mastering and composition. Also they have a samples forum where you can find some websites like KVR that have some great free stuff.
Be careful towards the end there where you have everything coming together. It sounds like you're on the edge of peaking too high.
Pretty decent overall though. I would recommend having a big big drop in there somewhere as well.
