I think the sound is totally fine though some of the guitar parts are just ever so slightly off time. It isn't my kind of thing, but for the genre I think you've done a good job overall in writing, performance and production. I don't think you've quite found your distinct 'voice' yet like a Mustaine whine or a Hetfield gruff growl but it definitely works for the genre. Well done overall.
