Theme Poster: Wonderland Opening

A grand theme park grand-opening poster in a joyful stacked layout, a central castle with blue conical spires and golden flags at the top, a looping roller coaster with an orange train curving around it, a ferris wheel on the left and a carousel on the right, confetti and balloons bursting across the sky. Bold rounded sans-serif headline in cherry red reads 'WONDERLAND OPENING', with a chunky yellow sub-line 'APRIL 1ST - FREE RIDE DAY' and small mascot characters at the bottom. Palette of cherry red, sunny yellow, royal blue and cotton white. Printed on glossy coated paper with spot-UV varnish on the castle. The poster hangs on a colorful kiosk wall beside ticket booths, banners fluttering. Bright sunlight from the upper left, morning quality, crisp highlights, short soft shadow. Wide shot, slightly low angle, straight-on view, vivid detail, 4k
