Visual Elements:

A solitary figure standing amidst a crowd, but subtly separated or in shadow.
Soft, muted color palette with a focus on blues, grays, and perhaps a touch of light to symbolize hope.
Background elements that suggest a supportive environment for others, but an empty space around the central figure to highlight their solitude.
Text Placement:

Incorporate the quote prominently within the design, ensuring it is easily readable.
Use a clean, yet emotional font style that complements the overall mood of the piece.
