Create a vision board collage showcasing a whimsical highland getaway. The centerpiece of the collage is a cabin nestled within picturesque mountains. Around the cabin, an enchanting tapestry of nature unfolds, filled with forest, wildflowers, and wildlife. The overall style of the collage is inspired by the colorful, cute and simplistic design aesthetics typically associated with the Kawaii Japanese culture. Please include text captions and phrases scattered throughout the collage that embody the calming and rejuvenating spirit of a mountain retreat.
