I'll try my best to challenge/advice you to grow your skills with this simple points.
1. Learn your WAV channel. Make awesome kicks, powerfull bass lines. The F command and H command can make your instrument go nuts. Search for a fuller sound (or whatever you want/need), try to imitate the sounds from another music that you may like. think in a sound and make it.
2. Invest some time layering your channels (E.G. 3 channel kicks/snare). Work on how one channel affects others, to make distinctive sounds.
3. Give room to everything that sounds, work your volumes and sound designs (don't overload some frequencies) so they can fit on to your ideas at your command.
4. Don't forget to make good music and have a good time. Practice a lot and be happy.
