Stills

I would be very tempted to shoot this straight on and wonder why you didn't. There is enough variation in each level not to look static.
 

I'm not sure that your off-square angle is working here.

Is that because the top of the wall is nearly horizontal?

As I've said before my approach would match Robert's but I like the stimulation to look for the angled shot.
 

I'm not sure what might work or not but I am with Colin on the off-square angle: but then I don't think that I would want square. I wonder if it is to do with the square format itself?

The door (is it a door?) is certainly fascinating but I'm not sure about its positioning: perhaps the desire to balance with the sign has something to do with it. But, not knowing the significance of the sign, I am not sure how important it is with relation to the title.

What I can latch on to is the Japanese block work and the nice gradation in tones of the receding trees.
 

This image doesn't involve me in the way others of yours have. Perhaps the wall is just too formidable for me—I have already admitted to exhaustion. The texture of the wall is certainly well captured.
 

The wall with a blocked off door(?) is quite in contrast to those marvelous airy tree forms -- which for me could make a picture by themselves. I wish to see that "door" opened.

I think straight on may have worked well, but don't really object to this angle. I wonder if our Western eyes that like to read things from left to right view this differently from someone who is used to the opposite. It seems to want to be read right to left.
 

Leaving aside the question of straight versus askew for a moment, it's the light playing through the trees that really draws my attention. For the sake of that light I could forgive almost anything going on in the lower half of the frame.
 

After initially viewing this, I felt that I needed to give it some time. By nature, I would have shot this dead on and squared the wall top and street, but that is me. Otherwise, the angles of the wall does not bother me.

I like the juxapostion of the hard wall and the leavey, soft trees, the angular wall and the free form tree trunks. The little sign on the left is very intriging and counter balances the larger middle gray panel on the right. Odd and interesting viewing experience.

PS - Sorry about the delay in response, we are in the middle of a two week driving holiday. And this monitor is not color calibrated and I have to use it as is;- (
 

Thanks for all the comments. These doors in walls are a pull for me and this one had no apparent means of opening from this side of the wall. The sign on the left is a no parking sign. I never really noticed how level the top of the wall was until mentioned and now it really appeals to me more so than the initial light that attracted me to shoot this in the first place.
