Promotion Of A New Superhero

Hello
My sister and I have a project of promoting an African American lady superhero series . She is doing the comic book part and I am doing the video part. I am trying to promote a Youtube superhero video on my channel with as many views as possible. The main thing I'm trying to do is to get more copies of a published comic book sold. Not sure if you can promote the comic book but the Youtube video with many views and likes will do well as we will be soon be putting together entire movies from the comic book in the future. Let me know if you can help. Thanks
