It has kind of the same problem like your last track. The two half of the track don't really connect. You have some wikkid sounds going on in the first half, and in the second you have the 303 sounds. Incorporate the sounds heard in the first half into the second half of the track, so that is sounds more like 1 track, that has build up.
About the kick. Make sure your monitoring on speakers that have a flat frequency response. Don't EQ your output at all. Set all your equalizer parameters on your amplifier, or reciever or equalizer to 0db, so that you can hear the track properly. You're probably used to hearing tracks with base and highs boosted to hell, so you try to do the same thing at home. But don't make that mistake.
A new kick sample layered on top of this one would be the best I think, since this one is a soft 808 kick with a lot of base. If you can find a 909 kick that has lots of attack and initial hit, it would add a lot of punch to it and life to the entire mix.
Also, use more effects, reverb, delay, chorus, etc etc to add some atmosphere to it.
and read up as much as you can on production. It's a must read for everyone home procuder. It has links to a lot of amazing information. My goal is to try to get through all the articles one day.
Otherwise the track is sounding really good.
What is Acid 3 like? I have Acid 2, but don't use it much except for time streaching functions.
Have you checked into Reason at all? I highly recommend it for you to try out. It costs about half a grand, but it's deffinetly worth it, and I think it can do a lot more than Acid, although Acid is really easy to use.
