enhance the realism of the small gray ballast rocks on the railway path while strictly preserving the original image composition and layout do not modify the geometry camera angle framing or placement of elements improve the material detail of the ballast by adding sharper micro texture irregular stone shapes and subtle variations in gray tones refine the surface quality of the concrete railway elements with realistic roughness slight weathering and natural surface imperfections increase depth through more accurate contact shadows and ambient occlusion between the rocks and along the concrete edges maintain the exact structure of the scene while improving texture fidelity lighting response and overall material realism
