First of all, the figure part is called silhouette in photography. You can find the material by searching for "jumping figure silhouette" in similar pictures on the Internet, and you can find the material by searching for "city edge line" in the background part and "triangle color block" in the filling part.

Secondly, after finding the materials,

1. Open ps, create a new layer, cut out the silhouette of the person you want, then cut out the map with the magic wand, cut out the city edge line with the magic wand, and then drag them into the layer.

2. Drag the triangle color block into the layer to cover the outline of the person.

3. Hide the triangle color block, select the figure silhouette layer, click the magic wand tool to select the figure silhouette, select the triangle color block layer, display the layer, execute the command bar above, select and reverse select. Then delete. In this way, the silhouette of the figure with triangular color blocks is made.

You can ask me if you don't understand!
