Portrait of an epic realistic angel with a deeply sad facial expression, a halo of light around the head, in a painting style reminiscent of French painter Alexandre Cabanel. The angel has striking blue eyes and is adorned with a delicate veil. The background is an old cathedral, softly illuminated by neon lighting, combining elements of 3D, cartoon, and anime styles. The artwork features a sketch-like quality, maintaining normal resolution and quality, with artistic emphasis on realistic anatomy and proportion. The angel is portrayed with a graceful physique, capturing the emotional depth and beauty of the scene.
