[Commission]SNS icon (cat-eared sister)

Commission Details
A commissioned character illustration for an SNS icon.
Creation Process
I received the character design. Based on that, I created multiple suggestions starting with a monochrome rough sketch, followed by a color rough sketch, and then finalized the design.
Concept
The character is causing mischief with a pen. The color scheme is designed to make the accent color of the character (yellow) stand out.
