The above picture shows you persons. And you see the picture is divided into three parts ( upper left, upper right and bottom half).
By exchanging the upper two parts of the picture, you get the picture shown below. But the below picture has only persons.
Where did the one person go ?

Its an illusion. that one person is adjusted in the other 14 as their heights have increased
Follow the eyes! And the scalps, and the beards, and the feet, etc.
It is an illusion created by the characters in the picture... The lines which divide the picture are placed so brilliantly that 2nd dwarf in the last column splits up... Hence this illusion is created....

There's a lot of variations on this idea, making things or areas "disappear". The trick usually involves subtle rearrangements of the parts in such a way that the sum of the area is still the same, but it doesn't seem like it. In this case, the 14 gnomes in the bottom picture are all slightly taller than the 15 gnomes in the top picture.

I agree with your statement.
The fifth person from left with long beard overlaps the face of the last person from right........hence only 14 people are in the next people
