Minimalist Education Method Logo

I’m looking for a clean, minimalist logo that captures the spirit of our teaching method. The palette is deliberately neutral—black, white, and subtle greys only—so the mark must rely on strong form rather than color to stand out.

The core concept is a simple child or human profile outline that cleverly incorporates the earth globe as the child or human being's brain to suggest language learning and international interaction as the basis for all learning experiences, especially for young people. Thin, even stroke weights, balanced negative space, and easy readability at both thumbnail and poster size are essential.

Please deliver:
• Editable vector artwork (AI and SVG)
• High-resolution PNG and JPEG on transparent and solid backgrounds
• A single-color inverse version for dark backdrops

I’ll review the logo based on the clarity of the the earth globe as the brain of the child (difficult to achieve without colours) and the purity of the outline of the profile of the child, teen or human being specifically and the outline of the logo more generally. The design should scale down to 24 px without losing detail.
