It seems way too plain.
It's true that good bass is required and you've got that =P.
I think you need more variation in the percussion. I also think you need better drum kits.
Also I think this is way too simple. There is no real melody on top. Nothing catchy.
I like the synth layering though. You just need something on top.
I hope this helps.
First of all thanks for writing me a review.
I see your point, and I'll try to work on it.
I'll try to come up with some other songs, maybe you'll like them.
With kind regards,
