This coloring page features a cheeky sheep with an eyelid on its head. The eyelid is just slightly ajar, revealing one of the sheep's eyes peeking out. The black nose and two horns atop the sheep's head add a touch of character and whimsy. The sheep's soft white wool is broken up by a cool black patch on its back. For a fun, yet subtle contrast, I would suggest coloring the sheep's face and horns in a light shade of grey while the patch remains a deep black. The eyelids can be shaded a warm yellowish-brown, ensuring the sheep's gaze stands out from the rest. The wool should be teeming with life, incorporating a variety of shades of white, grey and light brown. Finally, I would finish off the coloring page with a few accents — perhaps a vibrant green or yellow grass to frame the sheep.
