I instantly recognised the FL samples you used, particularily the pads.
(i use FL 4 too, you know)
Learn to use the Mixer, and work on your harmonies.
Slice some drum loops and try to find out how they are built up to learn about percussion.
Alternatively just use a backbeat with some cool hihats.. that always works.
You are not bad at all, my friend
Drop a few lines with me on MSN, and maybe i can teach you some tricks.
