I like how it progresses up to full effect but you could've made the drop bigger as in working the breakdown some more. Sounds pretty good, you've done good with few elements, the synth sound in the intro and just before the end is very good you should build something from that, because the bass itself isn't gonna carry the whole tune through for 5-6mins i think.
The kick hade some strange phase thing or stereo effect, i'd recommend narrowing it or setting it to mono. Low sounds can be problematic if panned or phased much. Other than that, production is good. You could add some sub to the bass but before doing it take another diagnose if possible because i'm on headphones at the moment. Definately worth continuing this one.
Peace.
