I used a new layer set to multiply and a vague Bevel and Emboss layer style to add some depth to the cracks.

我又新建了一个图层设置成正片叠底，通过斜面浮雕的图层效果增加裂痕的厚度。

Now create a new layer, set the blending mode to Soft Light, the opacity to 50% and paint with a large Soft Brush around the edges.

现在新建一层，混合模式为柔光，不透明度50%，使用大的软笔刷沿边缘涂抹。
