8. On the layer with our rectangle make another rectangle. Use fixed size: width -130px, height 450px.
Hit Delete.
Don't deselect!

9. Make a new layer, and fill selection with #515642 color.
Deselect.
Now copy Effects from 1st layer to top layer.

10. Now make new layer again (I've named it "dots").
Zoom your picture (1600%) , with pencil 1px and with white color draw the dots like i have. (Do you see? 8 dots ;) )
Decrease opacity of this layer: 65% is enough.
