Duplicate Layer & Gradient Tool

How To Duplicate A Layer & Use The Gradient Tool: 

You can continue the picture which you have resized just now. To duplicate a layer, you must right click the layer picture (Layer 1) and select "Duplicate layer".

After clicking the duplicate layer, you can rename it or just leave it.

After rename it, click the picture which u have cropped just now n drag it to where you want it to be placed.

After placing it in the right position, you can even resize the picture by clicking again "Ctrl + T". After resizing it, press "Apply".

You can even color the background by using another tool beside Paint Bucket Tool which is Gradient Tool. Gradient Tool is the tool where you can change the tone of the colors. Press right click on the Paint Bucket Tool and click on the Gradient Tool to use the Gradient Tool.

Then, click on a point and drag it to another point. Like me, I drag it to 45 degrees.

This is my product after using The Gradient Tool. This is the way of how to use The Gradient Tool to color the background layer.
