Stop seeking permission to create comics. The only thing it’s doing is holding you back.
When I made my first comic, I didn’t know much at all. I knew what a good comic looked like, but I didn’t know everything that went into actually making one. So I just did it, saving money and hiring an artist in order to help me bring my vision to life. Holding my first comic in my hands was like a dream come true. And I didn’t have to wait for someone to tell me it was okay.
There isn’t any real master plan keeping your comic out of the hands of the public. Diamond isn’t keeping you down. Diamond is in the business of making money, and if they can make money off your book, they’ll be happy to take it on for distribution.
Marvel and DC aren’t looking for you. They’re looking for someone who can bring more attention to their books. That’s as far as they really care about you. Very often, they will tell you that you should go and make books elsewhere first, and then they’ll either find you, or you can then come to them. (They want to see if you can not only make a book, but make a good book, and can replicate that on a monthly basis.)
You don’t need permission to make a book. You don’t need an editor or a publisher to decide the fate of your book. What you need is the fortitude to make the book and then to take it to a few shops in your area to see if they’re willing to carry it either at cost or on consignment. (You won’t make your money back this way, but that isn’t the point. Growing your comic business is the point, and it can be slow going.)
Stop seeking permission. Go create. Make an impact.
