I'm looking for an AI Pro to create a character animation for my product. The animation will be used for marketing or explanatory purposes. Since I haven't provided specific style references, you'll have creative freedom to propose a concept, character design, and animation style using AI-powered tools. The final deliverable should be a polished video file (MP4) and the project source files. If voiceover or sound effects are needed, please include AI-generated audio. The animation should be concise and engaging, effectively showcasing the product. Please share examples of past character animation work when applying.
