Hello, I'm Kevin Jordanus from Indonesia.
I've read your project details and i going to say that i am quite sure i am can be the right person in this project. i've done similar child book illustration outside this platform and i can do both manual and digital illustration, since you want this book to have comic and picture style, i think that will be great to combine both manual and digital approach.
about the 18 pages, i think i can do that around 45-55 hours, its about two weeks. I take this much time cause i think, i want to be fully grasp your story and deliver it in a best possible way that still have the whole message and visually pleasing for any age just like you said in the project details.
I hope I can be a part of this project, and i can hear from you soon.
warm regards,
Kevin Jordanus
