How to add cards under picture-elements?

Hello,
I have a picture elements tab and would like to include cards under it.
Could you please give me a hint how to do this?
I cant get it done to have a mixture of both.

Example of my picture elements card:

 - title: OG
    panel: true
    cards:
      - type: picture-elements
        image: /local/og.png

        elements:

          - type: image
            entity: light.bathroom
            tap_action: none
            image: /local/og_bathroom.png
            state_filter: 
              "on": brightness(100%)
              "off": brightness(70%)
            style:
              top: 50%
              left: 50%
              width: 100%

I use this card for my full set up. In this set up, your cards show up as elements. They will not look like the basic card set up. I’ll add a few pictures to let you see the difference.
