Illustrator/AI Needed to Create Personalized Children's Book Characters(expression&pose adaptation)

What I need is someone who can take the approved character reference (front and side views) and apply it to the existing character illustrations. You should keep the child's identity consistent throughout all images and (only modify the facial expressions as needed (happy, sad, shocked, concerned, etc.). The original poses, outfits, scenes, and actions should remain the same as the existing illustrations (holding a balloon, running, sitting, celebrating, etc.). The goal is not to redesign the character, but to replace the original character with the approved while preserving the exact same style, quality, poses, expressions, clothing, and overall artistic appearance.
