Cartoon Nature Coloring Book Page Design

I'm looking for a talented illustrator to create a simple, cartoon-style coloring book page with a nature theme. The page should be designed for adults, with relatively easy-to-color shapes and details for an adult colouring book.

Ideal Skills:
- Proficiency in creating cartoon-style illustrations
- Experience designing for adult colouring products
- Ability to create simple yet engaging designs

Expectations:
- A nature-themed, cartoon colouring page
- Easy-to-color but intricate shapes
- Minimal detail to keep it simple

The perfect piece would have mountains in the background, with maybe the sun or birds. The focus of the colouring page would be trees in the foreground.

There would be 10 trees, all in the foreground.
- 3 trees would be large in size.
- 3 trees would be medium in size.
- 4 trees would be smaller in size.

I have attached some examples using AI but it's not quite understanding the direction. The images I have attached I like. But the trees should be deciduous, so there are leaves to colour.

The goal of this sheet is for the trees to resemble areas or domains of a person's life. For example Work, Family, Friends, etc. There are three trees that would be healthy and thriving, three trees that are medium and four trees that are not getting enough attention.

I am looking for a price point for this design.

Thanks!
