There are a few things you need to know if you want to Photoshop wings onto someone. The first is that the wings will not be as realistic as if they were real wings. Second, the wings will not be as long as if they were real wings. Third, the feathers on the wing will not be as realistic. Finally, the skin on the wing will not be as realistic. To begin, take a picture of your person with their natural wings and then use a photo editor such as Photoshop to add in some Wings. You can use any color you like and make them very realistic looking. Once you have added in all of your Wings, save your file and then open it up in a new window or tab so that you can see all of your work together.
