Take a well-known picture of a famous artist and describe it using modals: must/can’t, may/might and phrases: in the foreground/background, in the centre/middle, on the left/right. don’t forget to mention the style, the colours and your own opinion.

This is a well-known picture of a famous artist. In this picture we can see a family. In the foreground we can see a boy who is standing with his schoolbag in his hand. It looks as if he has just come from school. He looks sad. He must have got a bad mark again and he is not happy. The dog is trying to cheer him up, but doesn't succeed in it.
 In the middle there are other members of the family. Mother and two children: a boy and a girl. The boy is riding his bike and the girl is doing her lessons. She is standing and opening a book. She might have started reading it when her brother came home. The mother seems to be upset but not angry. They all are looking at  the boy. The room is rather large and light. On the right there is a big table. I think the people usually have their meals there. On the left there is a desk with a lamp on it. I suppose that children do their lessons at the desk. There are some posters on the walls and a big clock.
In the background there is another room and it looks like the room is empty. At least we can't see anybody in it. Just a flower on the window sill and a picture on the wall.
The atmosphere is peaceful and we can understand that these people love each other and are happy to be a family. The colours in this photo are not very bright, but they are realistic – yellow, brown, red and white. It makes me think of an ordinary flat of those days. It is clear that this is a picture of a Soviet period as the girl is wearing a school uniform of those days.
I like the picture because it is very realistic and I like the expression of people's faces.
