This comparison focuses on sweeping curved strokes in Position 6 of Van Gogh’s *Self-Portrait* (1889), compared with matching brush formations in the Tree Oil Painting. The angular bend and torque rhythm within the cluster show significant overlap — both in pressure modulation and pigment dispersion pattern.
