The harsh vs. soft contrasts between the two images are doing war against the visual tricks unifying them. Nicely done with a message already noted by Abstract. -tv
apart from visual similarity and continuations, i like the conceptual similarity (both power) and contrast (wind-power vs electric) between them. -Abstract
nice how one shot continues to the next through the horizon(left) and line in the clouds(right). also good alternating light/dark balance in the four quadrants. I like this composition - b.c.
