Elegant medieval lady in green velvet dress by a gothic window

A full-length frontal portrait of a slender medieval lady, in a braided bun, with piercing blue eyes. She stands facing the viewer, her hands gracefully clasped in front of her, in a classic Renaissance portrait pose. She wears a long, elegant green velvet dress, richly embroidered with floral gold motifs, the delicate material reflecting the soft, diffused light streaming in through the large, ornate window behind her. The setting is a fantasy-style room, with ethereal, Gothic arches and columns adorned with gold ornaments. The soft lighting highlights the intricate details of her dress and the serene beauty of her face, creating a timeless, romantic elegance.
