蒸汽火车穿越拱桥与绿色山谷

Prompt: A vintage steam train crossing a high arched viaduct over a lush green valley, white steam drifting dramatically into a bright sky. Tiny figures lean from windows, and birds scatter as the train moves forward. The landscape rolls outward in layered depth. Rendered in refined painterly style with smooth blending, vibrant natural tones, and dynamic movement. Feel free to join in :) #AIArtWork #AIArt #AIArtists #AIArtCommunity #PromptShare
