Alright, well, first things first:
1. be confident in yourself, and never lose faith.
Thats one of the key variables that you have to consider.
When you're in a metalcore, post hardcore band, you'll cross a lot of people in this music scene where they hate you because of your looks, generic material, and just hate. Not saying that it's not okay to be generic. Be as generic as you can be

but, sometimes peoples words can get the best of you. You have to believe in your abilities, and write music that you are satisfied with. Never write music like this People>You. It's your band, and you can write however you feel is perfect!
2. For bass playing, try not to make it so sloppy:
When you play the bass in this genre, its hard to keep up with most things. Technical, progressive riffs, etc. Try and bring a little groove in your playing and everything will work out just fine
3. Always be positive and always make friends. In this genre, friends/fans/family are the only thing that keep it alive. remember that, FFF.
any other questions? Anything about tours?
