Transform Clipart into Cross-Stitch Art

I have a single PNG clipart file that I need converted so the entire image convincingly looks hand-stitched. Think high-detail work: lots of tiny, clearly defined X-shaped stitches that hold up when you zoom in, with colours, shading and outlines preserved exactly as they are now.

Deliverables
• High-resolution PNG with transparent background, matching the original dimensions
• The editable source file you create (PSD, AI or equivalent)

Acceptance criteria
• Small, uniform stitches visible at 100 % zoom
• No colour bleeding; edges remain crisp
• Overall palette and proportions unchanged
