Art style: Clean Line Digital Illustration.
Clean Line Digital Illustration. A nostalgic scene of a young boy building a perfect, symmetrical tower out of wooden blocks. He is focused and proud. The lighting is warm and golden, like a memory. In the background, a large storybook shows a castle with a golden key on the cover.
