Please ensure that the character's face looks friendly and approachable while maintaining a professional demeanor. Set the background to be a clean and simple white backdrop. The character's expression should convey both confidence and approachability. The overall image should be suitable for a channel profile picture, and a high-resolution image is preferred.
