This artwork is created using the acrylic technique, combining warm and cool colors to achieve visual contrast. The sky, with its soft blend of red and pink hues, evokes the feeling of a sunset, while the waves of the sea, painted with free and layered strokes of blue and green, convey depth and dynamism. The silhouettes of the dolphins and mountains are rendered in solid black, emphasizing form and movement, giving the piece a minimalist and dramatic effect.
