Create a new layer(below Elephant layer) and select Brush Tool(B) and right click on background to select skin and hair texture folder.

Step 10

Now we will remove nose with the Clone Stamp tool. Pick a soft brush. Set the size of the clone stamp so it will cover the object you want to remove. It takes some practice to know how hard and big your brush should be.
A good setting to start is a medium soft brush to achieve smooth edges. Move the cursor to the area you want to take pixels from. In this case I need sand. Use Alt-click to confirm your source pixels. The cursor will change into crosshairs.
The moment you click, the cursor will change and show the pixels you’ve cloned.
