Flat Digital Ecological Framework Illustration

I need a clean, flat-style digital illustration of Bronfenbrenner’s Ecological Systems Framework, but with my own wording in each concentric layer. I will supply the exact text for the micro-, meso-, exo-, macro- and chrono-systems once we start; your job is to lay it out so the hierarchy is instantly clear and the labels are legible at a glance.

Preferred style: flat design—no gradients, bevels or 3-D effects. The colour palette is flexible, so feel free to propose options that keep the contrast strong and the text readable.

Deliverables
• Editable source file (AI, SVG or layered PSD)
• High-resolution PNG and print-ready PDF

Process I have in mind:
1. Quick rough sketch or wireframe to lock the layout and wording placement
2. One revision round after I review the first coloured draft
3. Final files delivered once everything looks right

If you have portfolio pieces that show flat infographics or conceptual diagrams, please include them so I can gauge fit.
