I like the contrast of the subtle tones and the foreground pathways leading to the background. However, the background is decidedly far away and there isn't a lot to "hold" me.
Have you considered making a black and white? The light-dark contrasts of foreground and sky, foreground and downed trees would perhaps be more compelling.
I do like the tones of the image in B&W, but not quite as much as i like the rainbow of color reflected in the steam above the spring. Perhaps if I were to crop the image just above the rightmost cloud over the hill. That might make it seem less 'vast' and bring the spring closer to the viewer.
