Appearance is not a simple drawing. It is mainly to consider and define the user experience.

One thing is relatively clear. A good ID is for better products, and a good product is for better sales. An ID with evidence and logical thinking, and an ID that can be recognized and praised by the public. Personally, I think it is a good ID.
