Sarah,
Finally got it to load after I copied the link into real player...
First thing - I hate dogs barking
but that's just me.
The beat's okay but really repetative. Try adding some fills and change-ups. Oh, and swing it a bit more.
I like the "ohs" in the background...anyway of bringing them up in the mix?
Bassline is ok - I prefer them bouncy rather than constantly heavy - maybe inject some difference in that as well to make some varience...
Needs some more melodic elements I think.
Other than that, good effort so far! Keep it going
