It is finely painted and conveys a harmonious feeling. There are eye-magnets and interesting diagonals for the eye to follow. It's a good composition with interesting shapes. The red house reflects the colour of the skirt, which is fine. But maybe it competes too much with the girl and its colour should be toned down(?). It seems that the vegetation at the horizon is equally green as the nearby vegetation. Arguably, the colours closer to the horizon should be toned down more. As they become more greyish/bluish, it enhances the feeling of perspective. It's called aerial perspective. This method could be used on the left-hand grove to emphasize perspective, i.e. to make the farthest trees appear more dull.
Although the heaven takes up a large portion of the picture, it doesn't generate much interest. Perhaps dramatic cumulus clouds rising over the horizon could be added there, or a flock of birds. Alternatively, a dark rain cloud emerging from the left would emphasize the feeling of harmony through a contrast effect. However, it is a difficult problem, if one's intention is to relay a feeling of repose.
What adds drama to a picture is shadow and light. But there is hardly any shadow cast in this picture. It seems that the light is equally strong everywhere. It appears that the girl has equally much light cast on her from all sides, which is unnatural. However, one mustn't necessarily paint according to physical law. Highlight and shadow avoids monotony but is not easy to master. Rembrandt is known for his dramatic lighting. On the other hand, Vincent van Gogh found inspiration from Japanese prints, which don't contain much lightness effects.
