Or does the top center look like it's has a slight slope going left to right?

I think the railing is straight but the background behind that looks to be slopped and I believe that is what is throwing you off. I think I see what you are talking about though.

At first I thought the slope was an illusion caused by the different thicknesses (?) of the walls/arches on either side of the picture, but when I focused just on the walkway on the second floor near the top middle of the image it does seem to be slightly tilted. A slight CCW rotation should fix it.

I think the image is straight and it is some sort of optical illusion that is making you think it is tilted. I put it into PSP and overlaid a grid, and zoomed in a couple of times, and the horizintal railing at the top middle is as perfectly parallel to the grid line as is perceptable by my eyes. I think it tricks you because the vegetation along the left top "weighs" more than the bare counterpart on the right, and also because the tree in the middle has branches angled toward the left. Just my impression.

BTW, why did you use B/W ? Looks like a colorful scene.

Thanks for the input everyone.

One of the reasons I have it in black and white is because I couldn't get the trees to be a nice green. Plus I thought it would look better because of the lights and darks the colored version had.

Coolhar is right about 'weights' and how these effect our perception of balance in an image. Another contributing element in this photo is the ample distribution of darker areas on the left vs. the lighter right.
That alone is enough to toggle our sensory equilibrium.

It is very useful to learn and become aware of these phenomena, since they tend to bear very heavily on composition altogether.
