More set decoration - 2 images: one for the ground

and the other for some decorative cave elements.

Before adding the foreground to the scene 

we need to make a layer for it.

Create a new layer at the top and name it Foreground.

Drag ForegroundGround file into your Layout.

Change the origin to the Top-Left.

Change the position to 0 , 0.

To prevent accidentally selecting and moving the ForegroundGround image

Right-Click on it and choose Lock then Lock Selection.

Now carry out the same steps for the ForegroundSpikes

Remember to lock it as well.
