Create an ultra-high-detail isometric pixel-art timeline illustration (3:4, 4K), combining dense detail with symbolism and metaphor. The user has specified [Western Art Development].
First, reason about Western Art Development and determine: the theme title in both English and Chinese, the earliest and latest historical periods to cover, a fitting start stage label and end stage label, and 3–5 key evolutionary stages with their symbolic elements and color palette.
Then build an isometric "EVOLUTION MUSEUM OF Western Art Development" where each gallery zone represents a stage — so spatial progression equals temporal evolution. Use standard isometric perspective (2:1), rich layered depth, and smooth transitions. Assign 3–5 strongly theme-linked symbolic elements per stage. Use stage-differentiated color palettes to suggest time flow. Add bilingual pixel-font titles integrated into the scene: Chinese "[theme in Chinese]演进史" and English "EVOLUTION OF Western Art Development", plus subtitles showing the start-to-end span in both languages, and key timeline markers. Keep it professional yet visually engaging with interpretive space; suitable for academic analysis and comparative visualization.
