So, I want to have a bash at entering lj_photophile this month, since the theme is 'graffiti' and I adore street art. The problem is, I can't decide which of my many, many MANY photos of same to use. I've narrowed it down to five, please help?

( Five 640x480 photos under the cut. )

I can't post polls right now, so please tell me in the comments which you like best!
