This definitely looks abnormal. He is like a giant well-built man but with the bottom of a girl. Moreover, he is wearing a bikini. How strange is that now? Just look at the image closely however. You will find that there is a girl who has bent down just behind the guy. It is actually her bottom we are looking at. Since she is bent down, we can't see anything other than her bottom and legs. This is merging with the man's body who is standing in front of that girl and the effect is incredible and so realistic. Probably one of the reason is the fact that their skin tone matches perfectly with each other.
