How to fix it? This umbrella seems to be broken.

To retouch the picture to make the umbrella look worn, you can take the following measures:

1. Use a daubing tool or an eraser tool to trace some damage, crack or wear on the umbrella surface, which can simulate the situation of the umbrella after a period of use.

2. Adjust the saturation, brightness, contrast and other parameters of the umbrella to make it look faded or dim, thus creating an old feeling.

3. Adding some lines or impurities on the umbrella surface, such as getting some dust or water stains, or drawing some camouflage cracks on it, can make the umbrella look more worn.

It should be noted that these retouching techniques need to be used within a reasonable range and cannot be exaggerated or obvious, otherwise it will appear unreal or too artificial.

In a word, by adjusting the parameters such as color and texture, the umbrella can look more durable, but the best effect can be achieved by paying attention to the application and control of skills.
