Illustrative Classic Car T-Shirt Design

I want a single, eye-catching T-shirt graphic that appeals to kids, teens, and adults alike. The style must be fully illustrative—think hand-drawn energy rather than flat icons—and it should celebrate classic cars as the central motif. Bold, saturated colours are essential; no muted palettes or monochrome treatments here.

You are free to play with perspectives, motion lines, or playful typography as long as the final artwork remains family-friendly and print-ready. Please deliver:
• A layered vector file (AI or EPS)
• A high-resolution transparent PNG
• Colour-separated artwork ready for screen printing

Files should be sized for a standard 12" x 16" print area and remain editable so colours or minor details can be tweaked before production. I will approve the piece once it keeps its vibrancy on both light and dark fabric mock-ups without losing line clarity or detail.
