"Create a suspenseful, thriller-themed thumbnail divided into two halves

"Create a suspenseful, thriller-themed thumbnail divided into two halves. The left half should depict a dark, eerie, haunted house with a tense, frightened boy. This side of the boy should show him in disheveled clothes, with fear in his eyes and a tense expression. The haunted house should have a spooky, run-down appearance with shadows and a foggy atmosphere. The right half of the thumbnail should contrast sharply, showing a bright, colorful, happy place. Here, the boy should be in good clothes, with a wide smile and a relaxed expression. The background on this side should be vibrant and lively. The overall composition should be mysterious and intriguing, drawing viewers in with the contrast and hinting at a suspenseful, thrilling story."
