Cartoon Animal Game Illustrations

I'm seeking an illustrator to create drawings for children's games. The project involves designing and illustrating simple childrens items such as a tree where each leaf is a letter of the alphabet, or a number (1-10) where there are flowers each with a number, an animal parade for animals and a colorful chart for colors.

Requirements:
- Drawings of cute, small animal creatures
- Calm and friendly expressions
- Cartoonish art style

Ideal skills include:
- Proficiency in digital illustration
- Experience in creating cartoon-style art
- Ability to design engaging and friendly character expressions
