The sky looks so nice in this photo, I wish the image size were a little bigger. But as wonderful an evening (morning) this looks to be, it tends to distract from the focus of the challenge, ie, electicity. Pretty nice image though 8o)
This shot is too small to have any impact. I would have cropped in tighter to the lights and worked with what seems to be a nice background in the sky.
The image is very small, so it makes the image hard to judge fairly. For me the composition is poor, you need to take care of details like a straight horizon but also need to spend more time considering what your subject is.
Obviously your intention was to make a feature of the power lines, but the are very small in the frame and so it isn't clear whether they are the focus point of the image or not.
Hope I haven't rained on your parade too much, keep shooting and your eye will improve, just remember, composition is everything!
