Create a high-resolution close-up split portrait of a character with rainbow elements incorporated into their appearance. The portrait should feature a serene and mystical expression.

The character should be set against a backdrop of a waterfall or waterfalls in a natural environment, creating a peaceful and magical atmosphere. Use intricate details to capture the character's skin texture, hair, and other facial features.

Incorporate rainbow elements such as iridescent makeup, hair color, or clothing, to create a vibrant and fantastical effect. The overall effect should be sharp and focused, with highly detailed features that capture the essence of the character.

The final portrait should be vertically tiled, with one side in black and white, and the other in full color. The artist is free to choose which side will be in black and white.
