Who's the main character?
Does there have to be one?
I'm hardly an expert on writing – or much of anything, for that matter – but I know one of the cardinal rules of doing anything artistic. Someone somewhere is going to complain no matter what you do. Sometimes, that's how you know you've succeeded.
I've also introduced the members of a new, completely fictional, band. Their names are Meg, Jo, Beth and Amy. Beth plays keyboards, of course. I'm a little worried about those names, for obvious reasons. I don't think it's particularly clever, but they're minor characters. They're women, though I never mention their heights. They have to be called something.
