Thanks for all your comments, I actually thought about going back on a less cloudy day to get a better shot, but I had already submitted this one. This is my first entry to the challenge, and your comments have inspired me to submit more. Thanks.
There seems to be too much noise in the picture. You should try and photograph it when the sky is more interesting. The light pole seems out of place in the photo, and doesn't add much.
I like the gritty texture you;ve got here. How the blue of the spray paint mirrors the blu of the sky. The agnle of the sign and light post fit with the feeling of how unexpected and intrusive the sign is. Perhaps just a tad brighter?
I like the subject of this shot but would like to see some sky between the signpost and the lamp behind. One step to the right when taking this would have inproved it considerably.
