I'll admit: this has a serene tone to it. But the size of that building, the bright of day, that... cheekiness of the pastel colours tells me something else. I see life here, celebration, childhood games of pretend. This is like a sanctuary. One where peace and peace can mean two completely different things.
Those pecky strokes almost give this a hand painted feel. It's a nice effect. The desaturated colours used in the distance have been managed beautifully too.
