**Painting process and stroke structure – Position D (Starry Night vs. Tree Oil)**
Position D shows a similar painting method between *The Starry Night* (1889) and the Tree Oil Painting. Both works reveal a wet-on-wet technique: horizontal background strokes were first applied, followed by thick vertical strokes layered on top while the surface was still wet. The stacked impasto texture, stroke rhythm, and color drag behavior illustrate high procedural resemblance.

🎨 *Observation: Foreground torque layered over horizontal wet field using thick brush.*
