Thank you for leaving the discrete tuft of hair in the last pic!
You're onto it in general, now it just needs some fine tuning
I'd like to see more definition to his back legs all around, it appears he doesn't have very much angulation and I can't tell where the top of his hock is to know if it's set high or low. (Not a criticism, it's a question we have to ask ourselves when grooming for show--am I showing this off to the best advantage?)
Be sure to have someone move him for you after you trim to make sure you don't have any flying hair making optical illusions
