thats a first
Your doing a very good job bringing this kind of quality on NG. Or maybe your doign yourself short but hey:p
About the mix though. Your drums fade away in the guitar its wall of sound. Either compress them more to get a more punchier sound. or maybe a little more volume on the overal drum group is not a bad idea either.
The weird synthy sound at the end somewhere. Its cool but its not... know what I mean ? :p its a bit akward lets just keep it to that.
also your bas guitar could be more punchier. Maybe add some around 700Hz in the EQ for more finger detail.
I can ramble on for another 500 pages but I think I said the most important things :D
Keep it up, you got skills.
