Create a series of 3D cartoon-style character portraits and half-body images inspired by ancient Chinese poets. Use a soft and vibrant color palette based on the provided theme colors: #F9E7EC, #FBC6A9, #F69A8D, #FAA54A, #72CCD4. The characters should embody a blend of historical elegance and modern animation aesthetics, suitable for an educational app on Chinese poetry. Each character should have distinct features that reflect their poetic style and era, with a friendly and approachable expression. The background is transparent, and it is required that the portrait of the character must not exceed the image. The image should fully display the task avatar, including hair and various accessories. All characters are male, with a maximum of four.
