The man in the park looks incredibly jovial as he plays his accordion. His traditional black hat and long coat are the perfect complement to the bright red and white instrument. I think it would be great to color this scene with vibrant hues of blue and green for the park, yellow for the sun, and pops of red around the accordion. Additional touches of black here and there also complete the piece. Painting the musical motif with different shades of red and white will enhance the atmosphere of joy and music.
