'cept the fact it sounds like you're using NordLead or something from z3ta+, :(
whatever it is, fix your melodies man. :(
Sure you might not need a beat, but still, give it SOMETHING. It's just a synth and a bas. How about some subtle pads in the background, or strings to compliment the melody. Maybe a few "whoooosh" samples to bridge your transitions?
Consider some of that, oh and >:O
Tiesto's not the best, jeeze, everyone needs to stop thinking he is.
He's freakin' awesomely great, but he's NOT the best. In trance he's VERY VERY VERY good, but he's also EXTREMELY commericial, i think, :P
check out some of them dirty underground artists man. They'll show you whats up.
