I respect the work.
The Guitar work here is insane as well as the drums, but the vocals are lacking in quality. They're way too thin, and the harmony is off in alot of parts, and just sound like they were recorded on a 6 Dollar microphone. Invest in a studio quality Condenser Mic. Throw a bit of reverb on the vocals, throw on a few effects, double up the tracks, just fatten them up and you have a sweet thrasher.
