WhatsApp Sticker Modification

I have a WhatsApp sticker that needs some modifications. The sticker file is available, but I'm not sure if it's part of a sticker pack.

Ideal skills for the job include:
- Graphic Design
- Proficiency in creating and modifying stickers
- Knowledge of WhatsApp sticker requirements

Please note that specifics about design changes, text additions, or color updates have not yet been determined.
