Usually, it's pretty clear with the subject in your images / footage whether the content can be submitted as commercial or editorial. However, I'm unsure about skateboard parks. I have some images of an empty skateboard park so no people present. And there are no logos or brand names visible. However, it is a concrete skateboard park and a bit of creativity would have had to be involved to come up with the various shapes and slopes depicted with the skateable surfaces. Though obviously, it's not built as a work of art. It has a functional purpose - to be skated on. So I'm guessing commercial would be the appropriate category?

Oh yea it's one of the few skateboard parks Ive seen with no graffiti.

Commercial.
