Realistic Black Hole Pencil Illustrations for Book

I'm seeking an illustrator capable of creating detailed, realistic pencil illustrations of a black hole and other space elements for a book I'm working on. The illustrations should be intricate and able to capture the complexity of space. Specifically, for the black hole illustration, I need the following elements to be featured: - Event horizon - Accretion disk - Jets of particles - A cut-away section showing the inside of the black hole - A wide perspective of the universe The ideal candidate for this project would be an artist with a strong background in realistic pencil illustrations, particularly in the realm of space and astrophysics. Please provide a portfolio that includes similar work.
