The size of Canterbury Cathedral is small compared to either Westminster Abbey or St. Paul's. Larger, if I remember correctly, than Salisbury Cathedral. Each has its own distinctive features that make a visit worthwhile. I would like to spend a month or more touring all the cathedrals of England.
The camera I used to take this photo was cheap and poor quality- jpeg only. So after the fact (and many times since 2005) you do what you can to rescue a picture that could have been better. Of all the renditions of this shot, I think I like this best. I have learned a few tricks in Photoshop and Lightroom that help.
