You can do better
I understand that this is a beta but what's the point of submitting a beta? Might as well wait to finished the completed version eh? Well here's my review.
Beat:
Nice beat. Even though it was very complex and interesting, I found it rather boring after a while. If you had more than one layer of drums then it would liven things up a little. Try (VERY) different variations of the beats too. Like add a tiny breakbeat part of it's own at one time or another. That would sure wake up the listener.
Synth:
Rather oring and basic. yet again, I understand that this is a beta and you "threw it in" for "substance" but I am reviewing your work regardless. You could've tried for a nice melody of some kind instead of a droning sounding one. Maybe a highpitched synth with a nice melody could've made this ten times better. If the melody changed as often as the beat did without straying to ofar away from it's original melody then again, more points for you.
Overall:
Nice beats, crappy synths, mediocre piece of work. But I have offered you some tips and I hope you use them to improve upon yourself. Remember, it's not what you think sounds cool, it's what sells to the people best.
