nice work son
i'm a great fan of your main drum lines, your beginning drums were a tad annoying, i think the snare wasn't balanced against the hats properly.
Pointers could be fixing your kick, it delivers a click but it needs be a less like an acoustic drum kick and more like a club wub kick, it would suit the synth and sine better that way. I understand how you can get stuck when you've created an awesome synth and drum line but something is missing, i think it's the lonely sounding lead. it needs something i'm not sure, perhaps some ambient accompanies? it's a tricky one
that said, this piece is still great. i look forward to the completed piece
