Create a realistic product photography for a paint-by-numbers canvas featuring an image of a vibrant sunset over a field of sunflowers. The canvas should be angled slightly to the left to show its depth, resting on a clean, white surface. The lighting should be bright and even, highlighting the details of the canvas texture and the vivid colors of the sunflower painting. Include clean, modern graphic elements indicating ’24 Colors’ and ‘40x50 cm’ in the upper right corner, with the ‘40x50 cm’ element featuring a slightly more prominent, neon-pink outline. In the lower right corner, create a ‘Difficulty’ indicator with three filled stars and two outline stars, symbolizing a medium difficulty level, using a gradient blue to purple color scheme for the text and stars. The overall style should be clean, professional, and eye-catching, suitable for an e-commerce listing.
