Flexural cracks or punching cracks?

[MegKCB]

Hi All. We have been asked to write a report on a flat slab which has lots of cracks on the top surface, mainly at the column positions. I have uploaded a photo - do you agree that this is flexural cracking? This photo is taken on the top surface of the slab, at the column position. It is a square 450x450 reinforced concrete column. I am trying to confirm that this isn't punching shear cracking that we are seeing?

This has some decent photos, and it does have some similarities to your project.
