Difference in Pictures

Picture yourself a picture, yes, fairly bright, not quite ordinary, and maybe even beautiful. But why the two of them, because they're exactly the same, surely one is not enough? What's the matter? But the fact is, that in fact these two pictures only seem to be exactly the same, but in actual fact there is a difference in them. It is not great, and this is precisely the point. The difference between the pictures at first sight is not visible, but you should find it. To complicate the task you have set a time limit. Hurry up and try to find all the differences. Good luck!
