Owl Mascot Animations for App

I need a set of owl mascot animations for a React Native mindfulness app. The animations should cover four moods: idle, happy, sad, and celebration, across six growth stages. These animations must be delivered in Lottie JSON format. I am looking for a semi-realistic cartoon style with soft rounded shapes and expressive eyes. The color scheme should feature muted natural colors like browns and tans. Since I don't have any existing designs or references, original designs are required.

Key Requirements:
- Four moods: idle, happy, sad, celebration
- Six growth stages
- Lottie JSON format
- Semi-realistic cartoon style
- Muted natural colors (browns/tans)
- Original designs needed
- Include source files and commercial license
- Share samples and price for the complete set

Ideal Skills and Experience:
- Experience with creating animations for apps
- Proficiency in Lottie JSON format
- Strong design skills in creating semi-realistic cartoon characters
- Ability to work with muted color palettes
- Experience in delivering professional-quality animations with source files and commercial licenses

Technical specs:
- Size: 200x200px per animation
- Duration: 1-3 seconds per loop
- File size: Optimized for mobile (under 100KB per animation preferred)
Growth stages should show clear progression:
Stage 1: Baby owl (small, fluffy)
Stage 2-5: Progressive growth
Stage 6: Master owl (majestic/distinguished)
Context: The owl is a companion that responds to user performance in cognitive training games, growing as users progress.
