Is it okay to have a cloth with video projected on the front and shadow printed on the front when the back is polished?

The video is projected on the front. Can a piece of cloth print a shadow on the front? Of course, it can print a shadow on the front, because if one of his front projection videos is illuminated on the back, it will not affect his front. It is worthwhile to draw a front face without his shadow, but it looks less bright at that time.
