Airy,
Thanks for the comments.
It was not absolutely necessary to colour correct the shot because the concrete pavers were essentially grey with black outlines and the only other colour was the purple of the can. However, there was a touch of a magenta cast to the upper portion of the slide (possibly due to temperature damage to the film before it was given to me) which I eliminated with a bit of selective de-saturation, leaving the bright colour of the can alone. Had I done nothing, the image wouldn't have looked vastly different.
The image was scanned at about 600 DPI, which I always change to 300, and for me it has always been fine.
I tried to correct the tilt, but that results in a great deal of cropping being necessary, which eliminates the "sweep" of the shot from foreground into the distance that I liked. Similarly, that's why I didn't crop out the uppermost distracting elements, (as has been suggested as well at all the other sites where this is posted.) I left them in to give the image a deeper sweep from foreground into the distance and rationalized their inclusion as anchoring the shot at the top.
As for your comment on distortion, I'm not really sure what you are trying to say, and so no offense was taken.
