This was done in Blender using a winged head I sculpted a short while ago. I added a partial body & gave it a metallic gold texture, then lit it with an HDRI (high dynamic range image) as well as a sun light. By experimenting with the lighting, HDRI placement, composition, etc., I came up with the following images. The only difference between I & II is the rendering engine used (Eevee in the first, Cycles in the second). The results were suitably ethereal & heavenly, I think.
