This spooky monster is perched atop an open door, gripping the doorknob between its two stubby hands. Its beady eyes and uneven mouth are the only markings that distinguish it from the plain white of the door. To bring this monster to life, start by adding a deep black to the eyes and mouth, against a backdrop of green or some other frightful hue. Give the monster a dimension with some shading, deepening the tones around the knuckles and giving the monster's body a more defined shape. Finally, add a few extra bits of detail, like a cottony texture to the fur or a few jagged streaks of bright color along the edges of its face. Have fun and bring this monster to life!
