Composite render elements in Photoshop

Hello … I’ve searched through the forum but cannot find a good tutorial on how to correctly assemble rendered elements back together in photoshop.

I’ve rendered out an image with all of the elements separated.

Maybe someone can point out a link or tell me how to do that.

Thank you … Andreas.
