This beautiful illustration of a little polar bear standing on the edge of a cracking sheet of ice is quite captivating. The polar bear looks like it is daring itself to jump right in and explore the icy depths below. To enhance the mood of this piece, I would recommend using light blues and grays to emphasize the light reflecting off the ice and the cold, icy atmosphere of its environment. You could also use whites and airy blues to further accentuate the depth and feel of the water. For the polar bear, I would suggest using a light evergreen and beiges to create a subtle contrast between the surrounding environment. Finally, I suggest adding shadows and highlights to give the image an extra dimension and enhance the realism of the scene.
