Enhancing Syntactical Complexity

Consider the following excerpt taken from a fictional narrative:

"Striding through the withered fields, the sun dipping low on the horizon, she recalled the laughter that had once filled this barren space. An echo now suffocated by silence, it lingered like a ghost of memories past, reminding her of all that had once thrived within the embrace of life. Yet with every step, her heart grew heavier; nostalgia wrapped around her like a shroud, weaving both comfort and sorrow into a complex tapestry of remembrance."

Which of the following sentences would best replace the phrase "the sun dipping low on the horizon" to achieve greater syntactical complexity and maintain the original meaning?
