Average songs, decent well-placed solos, nice guitars, voice needs a lot of work. Without the voice, it just doesn't cut it. Either you you go the slow way with your voice instead of raunchy because I see more potential there and a more unique style. But you need better control of your voice when you lay it slow. At times, you pitch out and your volume loses emphasis.
There is potential but improvement needs to come form the voice first. Then write interesting songs and some good things may happen. But you must know that if you go raunchy voice that you're not going to do much other than the odd gigs right?
I'd rather slower voice and raunchy guitars. Clever lyrics. Good songs. These might make a difference.
Cheers!
