Grand Archway Made Smooth Shimmering Crystal

Create an image featuring a grand archway made of smooth, shimmering crystal. The archway should have intricate patterns resembling delicate flowers etched onto its surface, capturing the light at sunset, casting soft pastel hues in the background. Replace the person standing beneath the arch with a silhouette of a tree, adding a touch of nature. The ground should be covered in soft, white sand instead of ice, enhancing the serene atmosphere.
