el jacko takes pictures every now and then

You should take the following with a grain of salt as I've yet to acquire the funds for a camera and actually take photos. Though, it should provide a good insight as to what a normal person seems in your photos.

I'm especially fond of the first shot. The soft light reminds me of the smell of freshly printed newspapers, and the cityscape in the background brings back a stark memories of waiting for a morning bus after a long all-nighter of Calculus. Possibly your best shot.

The second photo is the worst of them all. It urges on a nagging question in the back of my head to the effect of "there's something you're not seeing". No, I am seeing everything, and the shot sucks.
Sorry

The focus of the third photo seems to be confusion, and it is extremely well done. It doesn't feel like a "well balanced" shot, but its key feature is superbly done. I especially like the blurred lights and the plain background - they add volumes to the lack of place and direction.

The fourth shot is odd. A plaque like that should be within a classroom, or perhaps an office - not near a cold steel fence with a daunting bridge in the background.
Why is her name printed? It would seem more natural to have a generic plate with the caption "A+ Teacher" and the name written in cursive, child-like letters as if it had been presented to the teacher by her students.
I don't like it. Wherever did you come across it?

The angle of the fifth shot seems wrong. I think your intent was to make it seem as if a mother has, in the midst of her conversation, turned around to check up on her children and is amazed to see what the children have drawn. And in that instance, the angle is wrong. Though the chair is is beautiful (neat texture <3), there should be less focus on it, and perhaps even less on the drawing. This is to make it seem as if the mother were truly turning around and could mostly see the cement, and only a bit of the drawing that has caught her eye. The plain-looking cement would serve to focus the viewer's eye toward the chalk-drawn figures.
(THAT IS IF THIS WAS YOUR INTENT - IF NOT DISREGARD THE ABOVE.)

At first, the last photo, like the second, seemed to be a generic snapshot in time. However, at the last moment, my eyes caught the lettering of the graffiti, and I thought it had said "slurp". Noticing that and the pipe below it that seemed to ooze the white pavement below, I was greatly amused.
Too bad the graffiti actually says "sulk"

Hope that helps.

Jam it back in, in the dark.
