See my other review ... (I'll stop commenting on your related tracks :P) Same thing. I appreciate that you're trying to mix up the bass lines and the drum patterns, but there's just not enough elements. Look at this way, let's say hypothetically you have 2 different ideas per instrument/element/thing. WIth drums and bass that leaves you 4 possibilities. If you add a third, that doesn't give you 5, but 9. It's exponential.
Not bad, though. :)
