Pronunciation & Vocal Tract Diagram Illustrator Needed — 29 Anatomical Illustrations

Project Overview I'm looking for a skilled illustrator to create 29 original vocal tract diagrams for use in a Japanese language brand. These illustrations will be used across branded educational content including videos, social media, and student study materials. What I Need 29 detailed, realistic side-view cross-section illustrations of the human head, showing the tongue, teeth, lips, roof of the mouth, nasal cavity, and throat. Each illustration shows a different tongue position for a specific Japanese pronunciation sound. The style should be anatomically detailed and realistic, prioritizing clarity over flat or cartoon-style designs. Each illustration must include: Highlighted tongue position (color) Small dots or circles to indicate where air exits Short plain-language labels (e.g. "Back of tongue touches the back of the roof") — no phonetics jargon A one-sentence pronunciation tip below each diagram All text must be delivered as editable text layers (do not outline or flatten) File Requirements Primary deliverable: Adobe Illustrator (.ai) files Additional exports: SVG + PNG at 1000×1000px, 500×500px, and 1080×1080px Transparent background on all exports Brand guidelines (colors and fonts) will be provided upon hiring Important A full detailed brief with all 29 sounds, reference links, and style guidelines will be shared with the selected illustrator. Please review the style reference image in this post before applying.
