Hello, I thank you for taking the time to explain your project, it is very clear. I'm interested in being part of it.
The question is whether the illustrations will be part of a printed work, comic vignettes, illustrated book or digital publication.
I am willing to work hard to obtain a good result and a language with personality that enhances your text.
My proposal is to start with 1 illustration and make this scene, one or several sketches. Once approved, make some samples of techniques, styles and color palettes. Ideally, for each illustration I can charge you $ 40, that is, for the 20 images $ 800. We can talk about it.
Thanks for you attention. I am available any questions, send me a message. I hope we work togheter and realize a good product.
