I think if you can't avoid to include powerlines into your frame then you best make them your subject! If they had been a sharp silhouette against this colourful background, your photo might have come out more convincingly. Blurred as they now are, they only look wrong, out of place, a nuisance (to me, who I have neither seen that sunset with my own eyes, nor do I live where you live and know all the surroundings).
