First of all the surfer will be lying down on his surfboard. This is because most first time surfers will lie on the board to get use to it.
On this slide the surfer will be kneeling on the surfboard. This is the first step to standing up and actually surfing. This reflects reality and shows that you are not going to get the hand of it first time.
On this part, the surfer will try to stand up. People manage to do this quick but fall of which is shown in slide 4.
In this slide, the surfer will fall off his board. This is a reality because every one learning to surf will fall off.
Now the surfer has learnt how to surf and is doing it correctly.
