English Description:
This comparative close-up highlights the deep grooves and vertical brushstroke pressure visible in both Van Gogh’s The Bedroom (1888) and the Tree Oil Painting. In each sample, the strong downward motion of the brush and tool marks carved into the thick impasto create channels of paint, revealing the painter’s physical intensity. The absence of varnish in the Tree Oil Painting allows the structural ridges and raw textures to remain sharply visible, closely echoing the tactile surface of The Bedroom.

中文说明 (Chinese Description):
此对比特写展示了梵高《卧室》（1888）与《树之油画》中的深刻笔触凹槽与竖向压力痕迹。两幅作品中，画笔下压的力量与工具刮痕在厚涂颜料（厚涂法）上留下明显沟槽，清晰反映出画家的身体力度。《树之油画》因未上清漆，使得这些笔触脊线与粗犷质感更加清晰可见，与《卧室》的肌理效果高度呼应。
