**Brushstroke curvature – Position E (Starry Night vs. Tree Oil)**
In Position E, curved strokes from *The Starry Night* (1889) are compared to matching swirls in the Tree Oil Painting. Both display thick, curved dragging motions created with a loaded brush. Despite differences in hue, the force and rhythm of stroke movement reveal a closely aligned gestural style, suggesting a consistent physical hand movement in both artworks.

🌀 *Observation: strong brush torque with curved drag, similar groove angle and weight.*
