In search of angel wings

I’m a photographer who loves to use Blender to enhance my photoshoots giving them props and elements that no one else has seen before. My next project is a medieval angel photoshoot with a beautiful model and a CG castle in the background that I made.

However to really make this shoot pop I want my model to have some believable angle wings and can’t find any props to fit the bill. Does anyone have any angel or large bird wing models I could use and incorporate in to this photoshoot? If I can’t find one any tips on creating detailed and realistic feathers for pose-able wings?
