"Craft a masterful oil painting blending expressionism and abstract expressionism, showcasing a group of dynamic Chinese figures performing the Guizhou Nuo opera, each character adorned with a wooden carved Nuo opera mask. Render the masks with a subtle, ethereal blur to introduce a sense of mystique. Structure the composition within a two-dimensional, flattened space, emphasizing soft brushstrokes alongside a palette of bright, vibrant colors. Utilize oil painting techniques to achieve this artwork, with a focus on employing 'rubbing, kneading, dotting, and wiping' to cultivate a rich texture. The application of colors should be thick and fluid, allowing for a dynamic interplay of paint layers that adds depth and movement, culminating in a pronounced oil painting texture. Ensure the overall brushwork is loose, with clearly visible strokes that define the characters and the essence of the Guizhou Nuo opera."
