Dmytro and Iuliia, artists in Ukraine, are masters of the silhouette. Their amazingly detailed works are hand cut from single sheets of paper:
By focusing on the positive and negative space, the artists are able to form each final design without breaking a single, continuous piece of paper. Plus, not only are their designs incredibly amazing, but the presentation of each design is photographed from a perspective that gives the illusion of such things as a paper eagle soaring across the blue skies or a young couple perched high atop the buildings of a city skyline.
