I like it, and it definitely doesn't sound like hell
I would just suggest that you guys incorporate more variety in your playing and your writing. especially with vocal patterns. Even subtle changes in beats, and riffs, can go a really REALLY long way when your trying to fit more sound into your songs. There's nothing wrong with repetition, but if the audience can guess your every move before you make it they're going to lose interest. The more technique and skill you utilize the better. The deeper your bag of tricks goes the more people will like you.
