Design a symbolic 8K resolution 3D double exposure artwork featuring a silhouette of Janus, the Roman god of beginnings, transitions, and duality, set against a backdrop of doorways, gateways, and temporal motifs. Within Janus's form, incorporate: His two- faced visage looking both to the past and the future A key in one hand and a set of scales in the other, symbolizing transitions and balance Flowing robes that merge into architectural elements of gates and doors Inside Janus's silhouette, depict scenes of beginnings, endings, and the passage of time: Doorways opening to new opportunities and closing to past events Clockwork and hourglasses representing the flow of time Scenes of transitions such as day turning into night and seasons changing Use a color palette that blends: Earthy browns and grays representing structures and permanence Soft golds and yellows symbolizing new beginnings and hope Muted blues and purples for reflection and transition The overall composition should convey transition and balance, emphasizing Janus's role as the guardian of beginnings and transitions. Incorporate artistic styles inspired by Roman architecture and symbolic art, with balanced, harmonious lighting effects to enhance the symbolic and contemplative atmosphere. Subtly integrate gateway motifs and temporal symbols throughout the artwork, symbolizing beginnings, endings, and the cyclical nature of time
