Opinion: They need more elements to them. Something to get your attention. You going in the right direction. I can hear that when you get more time and sounds under your belt you're going to be a beast.
Add a bass line to #6 with some crisp hit hat s and you got a feature that should be the first beat you hear when people come to your page. Some one told me to name my beats instead of numbering them. It does give it its own identity. You should only put up what you feel are the best examples of your work. People seem to judge you by your worst and not your best sometimes.
If you ever have any questions just post. We are a tight nit family around here ready to help.
