Overall impression: realistic with a touch of impressionism...probably from the purple flowers at the bottom. I particularly like the light filtering through the trees, though it seems there should be more breaks in it. The two silvery barked trees in the center of the piece appear to 'sharp' given the haze the light is filtering through.
Going back to my original, initial thought, it looks real. I could see myself sitting in that forest spot listening to the wildlife in the stillness of the morning.
