|Greetings from the Critique Club!
Okay, interesting image that has some potential.
Not having a clue what the original looks like, I don't know if you did any cropping or not. As mentioned before the centering of the pole doesn't really work for this one, if you had used the rule of thirds instead? Moving the pole to the left and having more lines on the right.
Also, the use of the power lines, with the right cropping and composition you could have them leading you in and out, coming from right to left would be different than most but I think it would work for this image. Have the line come in at the upper corner and out in the lower corner. Try to see if you can get one line to come in exactly on the corner.
The sky is rather dull, being basic editing, there's not a lot we can do about that except adjust your hue/saturation in blue and make it pop a bit more.
I like the pole being dark but so is the sky in comparison so you don't really get that element that makes it stand out like silhouette <sp?>, it just blends in a bit right now.
But overall not a bad idea for the challenge, just a bit more work and this could really make an interesting and outstanding photo.
I hope my comments help and Good Luck in future Challenges!
