I like most of the riffs. Initially I think I was getting the synth mixed up with the guitar reverb (I thought it was going to be all guitar at first). Perhaps it was my imagination, though every once in awhile some guitar notes sounded like they were tuned a little flat. Nice guitar tone & playing. Perhaps you could review my music at this link:

Thanks for the feedback
A few people have mentioned synth.. but there's no synth in this track! haha!! I'm using an ambient reverb, which has a kind of synth-y sound to it.. But yeah
There are violins/cellos at 1:40 though..
Everything's tuned to 432Hz, so this could be why it sounds a little different, but that is what I was going for
I'll check out your thread now! Thanks again.
