I think that this picture is more than 1000 words. If you described the picture in words and the other person reading it can draw the exact picture? Even if you write ten-thousand words to your mom, she will never get the picture right, NEVER.
For example, the dragon (above). You can never ever describe it, you don’t even know if the background is the sky or snow.
I think that the picture worth’s more than 1000 words because you can’t exactly describe the dragon or the picture.
