How can this PS effect of COS phase come out?

first of all, the original pixel of the photo should be high, and it is best to have a SLR.

then, the angle of the light to be photographed should be selected. So that the photos can be easily processed.

The possible processing steps of this photo are: dimming, peeling, liquefaction, copying layers, decoloring, adjusting color levels, adjusting colors, changing layer properties, Gaussian blur, merging layers and resizing.

because I don't know what the original picture looks like, it's hard to say exactly.
