Nice moment of light in the first, Doug, and the structure of the framing enhances the structure of the motif. Lovely.
To my eye, there is a somewhat jarring issue of geometry with the second. You've done a precise job of levelling the base of the image with the course of bricks but, optical considerations have meant that the spire itself is not vertical. If you took the ruler tool and inscribed a line straight down from the apex of the bellicose through the peaks of the arches below and then go to Image . Motion . Arbitrary you'd find that the correction might be surprisingly substantial.
The shooting of structural material like this is more a matter of geometry than of seeing. Choose a viewpoint precisely perpendicular to the structure and you'll be better placed to retain the geometric integrity. Essentially the planes of a structure are best recorded if you treat them the same as shooting in the plan mode of the copy stand but swung to vertical rather than horizontal.
To the extent that I am able within the limitations of the window edge, it is only off by a poofteenth, if at all, and there may actually be an optical illusion of a warp due to the fact that the wooden cross does not rise from the exact apex but from slightly to the right as we view it.
