I downloaded Acid Dreams from the first link no problems...
To be honest you've drawn it out far too much, there's no basswork, just sequences and percussion... as I'm listening at around 5 minutes it's building somewhere, BUT it's just too repetitive - the same sequence repeating for 15 minutes is just a bit silly in my opinion.
You need to get some sort of bassline in there to thicken it up, even some pads in your breakdowns, try and put as many layers in there as you can... and there's not enough there to last for 15 minutes... I switched it off. Hold my attention!
Also I noticed that those samples are from FL itself, try and get some nice free stuff from the internet, there's plenty around.
