You've identified your subject, the tricky part is expressing what you want to say to others in a single picture. What is it you want to say?
In your example photo, everything is in focus, there is little contrast between the post and background, and everything has vertical lines. How is the viewer meant to know what parts of the photo are important? What is it you want to show people?
The pole decoration incorporated into the banner? http://www.flickr.com/photos/mochiland/205416509/lightbox/
The pole in its environment? http://www.flickr.com/photos/lhirlimann/4375549238/lightbox/
Something a little more 'dynamic'? http://www.flickr.com/photos/cogdog/2773153913/lightbox/
There's a ton of information about 'composition' on the web just waiting to be Googled. Some of it good, a lot of it so-so. Take it all as suggestion, rather than set-in-stone rules - as you develop as a photographer, you'll find your own way to do things.
Study photos you like (your own and other people's) - work out what it is you like about it and how it was done. Shoot as much/often as you can - to improve you need practice, practice, practice.
For starters though, direct people to what they should be looking at.
(The links below are just extrem'ish examples grabbed from a quick Flickr search.)
Try separating your subject from the background (differences in colour, brightness, focus). http://www.flickr.com/photos/southen/5610096056/lightbox/
Draw attention to your subject - contrast between subject and background, lines pointing to the subject. Have a path for the eye to follow to the subject. http://www.flickr.com/photos/mecan/81470204/lightbox/
Is size important? Give a sense of scale by including something that people know the size of (eg a person, car, or building). http://www.flickr.com/photos/gabricabri/5713429646/lightbox/
Is the subject of out place? Show how it is different from others (eg a giraffe pole peeking out of a row of normal light poles, or the giraffe pole 'eating' a tree).
Before raising the camera to your eye, compose the photo in your mind. Know what it is you want to capture, then position yourself and make the photo.
