The cobblestone streets of the old town seemed to sparkle under the afternoon sun. Leo quickened his pace, his steps light and springy. Every single thing felt perfect.

He entered the small, independent gallery, its windows displaying the promise of beauty within. He scanned the room, a slight tremor of anticipation running through him.

And there it was. His mosaic, a vibrant depiction of a mythical creature. It looked amazing. He knew it was the best thing he had ever made. He felt a deep, warm sensation spreading through him, a feeling of contentment and quiet exhilaration. He had to restrain himself from whooping with pleasure.
