复古风羽毛钢笔书写滴落商业照片

C4D render, ray tracing, high resolution. A white goose feather quill pen, made of delicate, textured clay, with its tip cut into a sharp nib. A single, glossy black ink droplet (deep black gradient) is suspended from the nib's tip, about to fall. An antique, calligraphic tilt. Warm, literary and ink-pot-era lighting on pure white background.
