When you’re starting out, any non-relative critique is a good critique. Doesn’t matter if the person is a great writer or not. It’s important to experience your work through another’s eyes. Writing is about communication. You can’t communicate until you know how you’re being heard.
So, how do you find a critique group? My crit partner and I met through BOOST (which became a paid service and now I can no longer find.) It was free back then. We were randomly chauffeured into the same online group with a moderator. I’m still friends with some of those gals. But the point is, join any of those free online critique swaps and get your feet wet. Along the way, you’ll find some folks like you and you’ll split off into your own group.
Some folks like to gather groups at the Blue Boards or the Yellow Boards or the SCBWI boards. That’s fine if you want to do that, but I feel it’s hard for a single newbie to break in. But, if you meet a friend on a larger critique site then you two ARE a group, and you can go advertise on those boards for people to join your group. You will have no shortage of applicants.
A third way to find a critique group is to take a writing class. In my experience, most writing classes force you out of your comfort zone into personal critique land and the group trust lasts long after the class itself is over.
Regardless of how you go about it, critique is a very important part of being a good writer. Not so much that we CAN’T write well alone, but that nothing past your first manuscript draft is ever done alone, so critique ends up being a part of your everyday life anyway. And we want to make all our embarrassing mistakes with peers, not the editor, right?
