Create a subtle grayscale bump map from the attached mural, with soft low-relief depth. Trees, leaves, and branches should appear slightly raised from the background, with smooth height transitions and balanced grayscale values. Remove all color, painterly effects, lighting, shadows, and atmospheric depth. Keep only clean grayscale height information.

No color, no beige, green, or brown tones, no illustration look, no watercolor effect, no lighting, no cast shadows, no highlights, no atmospheric depth, no 3D render, no perspective, no blur, no artifacts, no normal map colors, no blue or purple tint. Do not keep it as artwork — convert it into a technical grayscale bump map only.
