And we’re finally done with the background of our image. To clean the workspace, select all the layers and groups below the Cave group and add them to a new group called Background.

Step 12: Adding some life to the cave

Let’s add some life to the cave now. Open the Lily 1 stock, use the Quick Selection Tool (Shortcut: W) to select it, and copy and paste it into our project. Make sure that you paste all the elements of this step between the Cave and the Background group.

Use the Free Transform Tool (Ctrl/Cmd+T) as usual to resize it. Remember to hold Shift while resizing to maintain proportion (we don’t wanna lose the proportions in this step).

• You can also use the Free Transform Tool to rotate the image, just click outside the image and drag the mouse around to rotate it
• If you hold the Shift key while rotating, you will increase/decrease 15º each time
