first off, your picture is very small, see the tutorials on how to save for web, also you might try boosting your saturation levels to bring out the sunset, I like your composition
Welcome to DPC! One thing you shold always do is make sure you use the full size available to you when submitting a picture. People will generally score quite low for smaller shots.
These are lines alright, but apart from that I can't find something interesting in the photograph. You could also submit a larger photo (almost 2.5 times bigger).
