It is hard to understand how to fix the image without an image, but you might try adjusting your lights. If you are using spots (like a 3-point lighting setup) you can set their distance to just reach the character but not the backdrop. That might give you some options for lighting them separately. Another alternative is to render a "shadow pass" where the cyclorama is textured plain white. Now you will have 4 layers: the cyc, the shadows on a white cyc, the wings, and the character with alphachannel. Some creative layering (darken) in your photo app will allow you to blend the shadow layer over the background layer. holly
