meh, you guys should practice just song writing in general. and the vox are kinda strange, i get the metalcore vibe /papa roach meets tagtgren kinda thing. you should try and create more depth with your guitars, and what i mean by that is, dont just play one note, try to add something else to it.
but overall, not bad if its one of your first bands.
you guys remind me alot of one of my old bands, prevail, we didnt have alot going on in our music, mainly because we were just exploring the whole song writing thing, and really wasnt familiar with what worked and what didnt.
but basically keep trying to write, and dont write a part for a song just for the sake of writing a part. if youre not happy enough with something, then dont leave it in.
