Good luck at the show! I know you don't show AKC/CKC so not sure what hair cuts you do for UKC but I had some fun drawing lines for what I (fairly beginner at showing CKC) would try to do for AKC shows. (Hope if don't offend at all, It's good practice for my eye for doing the trims you'd see in CKC!)
Mostly shortening the back by the tail adding a bit by the pin bone, bringing tuck up forward
I would shorten all over on this one to create a tight compact dog.
I really like that 2nd last pic. He's got a lovely face/stance!
