There is something wrong with that image, I suspect the people where photo'd in a studio with carefully set up studio lighting and then added to the background image, then some carefully positioned lens reflections added on top.
The underside of the child's legs are in full shadow while the underside of his arms are well lit and most of his face and chest which should be in shadow is lit by a strong golden light, either from a lamp or a reflector.
He looks like he is having fun on a trampoline. Don't think he would have the same expression if he had been thrown up by those arms, as there is no way they are going to catch him!
So the answer to the question is that you need to put a lot of work into building an image like that, even with a GoPro, and it doesn't actually look like a GoPro image anyway - it has used a much narrower FOV lens, with a GoPro lens the top of the tree would be much smaller relative to the bottom.
