Children's book illustration

We need 12 illustrations for a children's book that will be used as part of a marketing campaign. You're illustrations will be briefed quite specifically, to match the storyline which is already written.

In terms of style, we're looking for bright, happy, uplifting styles that can be used to tell stories about nature, adventure and families.

I've attached a moodboard for reference, but we are very happy to consider your own style.
