At the picture we see a couple: a boy and a girl.
They are sitting at the coast of the sea looking where horizon is.
Probably, there is a ship, but we can't see iy because of the cloud far away.
at the right hand top corner we can see two gulls flying as high, that we can hard see them.
At the left hand bottom corner we see a small bush where the boy lay.
I can say, that the weather is not very good, because we can see waves that roll at the coast...
