Double exposure, a unique artistic style, is used to create dynamic and visually stunning images. This style combines two or more photographs into a single picture, resulting in a unique blend of colors, patterns, and subjects. In this case, the artist chooses a double exposure style known as Neumorphism.

Neumorphism is an illustration technique that utilizes bold, rounded shapes and muted colors to give images a 3D, tactile appearance. This style works well when combined with another style, like double exposure, and can create impressive visuals. In the artwork, we can see a young child dressed in pastel colors, standing in front of a blackboard. The visual is enhanced with overlays of pastel gradient and soft shadows, giving it an ethereal and dreamlike quality.

Complementing the double exposure style, this artwork is also adorned with other techniques. For instance, it has a shallow depth of field giving the subject a clear focus, while the background is blurred, contributing to the surreal atmosphere. This selective focus approach, known as bokeh, further emphasizes the central composition.

Adding to the visual experience is a stylish lens rendering – creamy light falloff and glassy reflections. This technique helps add a dreamlike and artistic quality to the picture, blending perfectly with the double exposure and Neumorphism styles.

In summary, this artwork uses a double exposure style called Neumorphism to create a unique and mesmerizing image. It features a young child in front of a blackboard, with pastel overlays and soft shadows, bokeh, and lens rendering techniques adding to its ethereal, dreamlike ambiance.
