You should really put this post in Collaborations, where writers and artists reach out to work with each other. Also, you should read this post for how to write a good collaboration pitch: https://forums.tapas.io/t/before-submitting-your-collaboration-request/41606
It's always good practice to give people an idea of what the project is, how long you expect it to be, what the story and tone and genres are, things like that, so any artists who may be interested will know if your protect is suitable for them or something they would enjoy doing.
