### Full prompt
```text
Infinite recursive Droste spiral based on the reference illustration. The original illustration serves as the prominent foreground image, duplicated infinitely toward a central vanishing point along a mathematically precise logarithmic spiral. Each recursive duplicate is scaled uniformly to [90%] of the preceding one and rotated by a constant [15°], maintaining consistent spacing, scale step, and rotation angle. Every iteration is an exact replica of the original with no distortion, cropping, stretching, or redrawing. Preserve the original artwork's colors, linework, shading, texture, lighting, and proportions completely intact, creating a seamless Droste tunnel with mesmerizing optical depth.
