Hi Jamal — glad you found it helpful. A portfolio is a good thing to have, but may not have the results you’re hoping for with regard to a publisher.
Most of them want to know an author has enough of an audience to help sell books. If they had to choose between Author A with a great portfolio and Author B with a lousy portfolio and big audience, most will take Option B.
If you’re clever, you might be able to leverage the portfolio development into an audience. Thanks for reading! :)
