not bad. .
I liked what you had going with the bass, there were some mixing issues though, I think the drums were too loud (especially the snare, if you boost something like that too much it gets annoying very quickly. . .)
Also the bass didn't have enough bass IMO it sounded more like a deep guitar than a bass, Basically more power! (cap'n I'm giving it all she's got! :P)
I liked your timbres (instruments if you didn't know, people don't seem to know that around here . . .) they go together well, just mix it a bit better and extend it!
Your ending sounded good though, simple but I liked it.
Not a bad start but it could use some work :|
