Gently rising hills block the view into the distance; line the wishes and desires of the children, who enjoy the blissful moments of the present with… - Caspar David Friedrich

If a painting has a soulful effect on the viewer, if it puts his mind into a soulful mood, then it has fulfilled the first requirement of a work of art. However bad it might be in drawing, color, handling, etc.

I just stepped out of the dark, still forest and found myself on a rising hill. In front of me I saw a valley, surrounded by fertile hills, in which a town stood and the newly covered slate roof of the tower glowed in the evening light. Through the richly-flowered, carpeted meadow the river meandered.. .And behind the hills lay the mountains.. ..cliff after cliff rose far out into the horizon.. .Filled with soaring joy I stood there a long time and looked at the beautiful area..

Sometimes I try to think and nothing comes out of it; but it happens that I doze off and suddenly feel as though someone is rousing me. I am startled, open my eyes, and what my mind was looking for stands before me like an apparition - at once I seize my pencil to draw; the main thing has been done.
