You perfectly projected your thoughts onto this picture. Yes, the effect of broken glass is created, as an option, you can find a glass workshop, or a workshop where broken car windows are replaced and take a picture of such glass. Try to photograph it against a light background. Then, adding contrast to the photo, remove all the white field, leaving only the cracks on the glass, this will be a great and very original filter layer for future work, if this idea comes into contact with them.
