Creative Material Image of 'Feedback' Written with Chalk on Blackboard

Description

Against a minimalist dark blackboard background, the word 'feedback' is written in white chalk with an artistic handwritten style. A small piece of white chalk stub lies scattered on the right side, with chalk dust naturally scattered around. The strong black-and-white color contrast creates a professional and clear business/teaching atmosphere, conveying core concepts such as feedback collection, customer opinions, and satisfaction evaluation. It is a creative visual material suitable for scenarios including service evaluation, opinion collection, and quality feedback.
