Cartoon T-Shirt Illustration Needed

I’m ordering new work T-shirts for our small, family-run car lot and need a single back-print illustration in a fun, cartoonish style. Picture a cosy garage interior: our lone mechanic—overalls, friendly grin—leaning under the hood of a compact car while our dealership logo features clearly on the vehicle’s door or a nearby toolbox. The scene should feel warm and approachable, reflecting the “everyone knows your name” vibe of our business.

Please design the artwork so it reproduces crisply on the back of cotton shirts. A vector file (AI, EPS or layered SVG) is ideal, along with a high-resolution PNG preview. Keep colours bold but limited enough for economical screen-printing; four to six solid colours usually work well. Shirt size template is 12" wide max, with transparent background.

Acceptance criteria
• Cartoon illustration set in a garage interior
• Mechanic actively working on a car, logo clearly visible
• Print-ready vector plus flattened PNG at 300 dpi
• Colour palette suited for screen-print (≤6 spot colours)

If questions come up about logo placement, palette tweaks, or exact shirt dimensions, just let me know—I can supply our existing logo files and mock-ups right away. Looking forward to seeing your style bring our little dealership to life!
