Flat vector illustration set that stays on brand

Draw a set of {{n}} flat vector illustrations for {{where they'll be used — empty states, a pricing page, onboarding}}.

Fix these before drawing anything, and hold them across all {{n}}: palette of exactly {{list 4-5 hex-ish colour names}}, one line weight, one corner radius, one shadow treatment (or none), and a single perspective — flat straight-on, no isometric mixing.

The scenes: {{list them, one line each}}.

Every illustration must work as a {{200px}} thumbnail, so: one clear focal subject, at most three supporting objects, no fine texture, no gradients beyond a single soft tint, no outlines thinner than the fixed weight.

No text, no UI chrome, no faces with detailed features. Transparent or single flat background.

Render them as a contact sheet in one image first, so I can check they look like siblings before you produce them individually.
