Create a full-length rendered image featuring Velma Dinkley, utilizing the male figure of Richter Belmont for the body structure. Ensure that Velma's head, including her distinctive hairstyle and facial features, remains unchanged and intact. Modify Velma’s original costume by incorporating embellishments inspired by Richter's attire while adjusting the overall design to fit the new male proportions appropriately. The image's background should elegantly blend visual elements and themes drawn from both characters, capturing the essence of Velma's mystery-solving world alongside Richter's gothic surroundings. Aim for a dynamic and engaging composition that highlights both character influences.
