How to change positions of controls separately?

Question

C++ / C#

Hello, I am creating a project in which I need to create a map with the ability to add a background. I managed to create a control in which 2 PictureBoxes are created, on one of which a map is drawn, and on the other a background is drawn. It turns out to rotate them separately, but when you rotate two objects, they move out. I have tried several methods:
1. First transform the background and draw it, then transform the map and draw it.
2. Create one big matrix and try to draw the background and map together.
