写实风格红砖建筑现代玻璃幕墙学院行政机构广场场景商

This is a composite architectural photo made from multiple images. I have already stitched together the main structure, but the surrounding environment—including the ground, sky, and the transition between the surroundings and the building—was not handled well. Please help me adjust it while keeping the canvas size unchanged. Ensure the building's dimensions remain the same without adding or removing any structural elements.
