Saw a review you left on Pixel's page, so I thought I might give you a listen.
For homemade synths I guess I can't be too hard on it, not that the synths are bad, I just feel like they don't meld together like they should.
My biggest gripe about the piece is that it feels like there's too little going on; there's big pauses in the melody that I feel like shouldn't be there.
As far as chord agreeing goes, it's a trance piece, so I guess that the slight discord is intentional and adds into the idea that it was supposed to be trance, but I definitely felt like this was a drum and bass throughout despite that I feel like the synths weren't meant to be bases.
Overall not bad, but I think it could use a good bit of tweaking before the finished product.
