This is one of my favorite photos I've taken (from April 27, 2013). What do you think about it?

I'd agree - though I have no idea who I'm agreeing with - IMO, you've shown us too much. Or you've shown us too little. Or you should have shot in portrait view. One or more of those.
In other words, you have captured the colors and textures well. The addition of the graffiti is a matter of what you are trying to tell us about the image. It doesn't bother me that it's there. It makes me more curious about the history of this subject. However, it doesn't answer any questions about the history. Possibly, that wasn't available. If you include it in the image though, I'd rather like an answer.
IMO your composition could be improved by a more discriminating viewpoint. I think you were mostly captured by the colors and textures of the image and might have missed the strong lines you might have shown. I would have at least looked at the same image in B&W in a preview shot and made decisions based upon the what the lines did to eye movement as opposed to just the colors. For colors and texture, very nice. For wanting me to look more closely at the variety of lines and textures in the shot, could be a bit more refined IMO. But, then, I sort of like lines and negative space. So ...
I understand most of us who go out to gather some images are taking shots in the available light we find at the moment. And in this shot, there's a certain appeal to the overcast look of what appears to be a cloudy day. I'd really like to see you go back to this spot though and get a few shots in bright(er) light which will have more dynamic contrast. Something that really plays up the composition's lines. And, if you do head back, think as you look at the image how to direct the viewer's eye to a strong focal point.
As usual, it's a keeper. Look at it again in six months and consider what you could have done differently. Come back to this thread and give us your critique.
Keep at it! It's a great start, just needs a less standard look IMO.
