As the creator of this oil painting, I attempted to capture the unique atmosphere of Budapest on a rainy night through this work. In the picture, the technique of fragmented oil painting and 3D relief effect are fully utilized to create a dreamy and realistic three-dimensional visual experience.

The core of this painting lies in its unique fragmented oil painting effect. Through the layering of colors and the interweaving of strokes, the image presents a texture as if it is about to melt. This effect is not only a visual enjoyment, but also an emotional resonance, making the audience feel like they are in that humid rainy night, feeling the dampness and coolness in the air.

The castle in Budapest occupies an important position in the painting. The details of the building are vividly portrayed through delicate brushstrokes and rich colors. The spires and architectural contours appear particularly solemn and mysterious under the dim lights, as if telling the history and stories of this city.

The atmosphere of a rainy night is achieved through the clever use of color and light and shadow. The blue purple tone in the picture not only enhances the depth of the night, but also makes the entire scene more dynamic and vivid through the treatment of fragmentation.

In addition, elements such as streets, vehicles, and street lights in the picture also add a lot of color to the overall atmosphere. These details not only enrich the sense of hierarchy in the picture, but also highlight the tranquility and loneliness of the rainy night through their silent presence.

This fragmented oil painting attempts to convey the unique charm of Budapest Castle on rainy nights through the perfect combination of color, light and shadow, and brushstrokes. I hope that when the audience appreciates this work, they can feel the depth of tranquility, the beauty of loneliness, and the urban charm intertwined with history and modernity.
