i've been makin beats for a few months now and i've noticed a problem with each of my beats . .

go to http://www.soundclick.com/FARSONN and listen to my beats . . .

notice something?

they all sound "empty" like they're missing something and they dont have that professional sound that most producers (even on the net) have . .

i know this is a hard question to answer, but i wanna know how to make my beats more "full" and sound more professional

it's hard to explain, but if anyone can share some advice, tips, experiences, whatever, it would really help
