Just because you worked hard doesn't mean that the product of your effort meets the standard. If your work is shoddy, it must be re-done, either by you or by someone else. I know that you didn't want to hear that I cannot let our clients see what you produced. Believe me: I didn't want to have to tell you that.
I'm still not going to let you show it to them. Tell your friends that I'm mean and unsympathetic - after you've produced something I'm willing to put my boss's name on.
