Artist Willie Hsu creates haunting sketches of people and animals that appear as though they’re trapped behind frosted glass. Each eerie shadow drawing incorporates clever shading that makes the figures look three-dimensional, as if they’re trying to reach out from the confines of the page towards the viewer. Human hands and animal paws are rendered with dark, detailed shading to appear as though they’re resting on glass, while a ghostly silhouette of the rest of the body lingers in the background.
