整体颜色的蓝色调浅了一点，增添了一些加亮曲线使渲染图更真实，又增添了一些小图案将渲染图前景的较低部分变暗。

I tweaked a bit the general color to be less blue. Added a bit more highlight curve to make it more "punchy" and added a light vignette to darken a bit the lower foreground part of the image.

通过减小或增加亮度来加深或减淡颜色，具体取决于混合色。

Burns or dodges the colors by increasing or decreasing the contrast, depending on the blend color.
