I liked the intro melody, it was nice. The kick is ok, but I guess since your restricted to the FL demo it's ok. Alright, the change is weird, but once again, it's the demo I guess. The second melody is alright, not as good as the first. The hat is a nice sample, but it's to repetitive. The kick roll was good, but maybe try putting a crash at the end of it?
Thanks for reading,
