Less and slower work.
Since a feature of Juniper is Jin and Shari, deadwood, there really is no rush to remove anything to fast since reverse taper can simply be cut out and made into a feature.
If keeper peices are being severely shaded, you can just wire things into sun.
From here I would like to see about 3x the foliage to safely repot, so now you're sitting for awhile. Which means get more J's.
Best to apply the cup theory. Where the amount of foliage stays near the same as it was when you bought it for it's entire life, since we know it is healthy at that point.
Shape a grown keeper section, and remove some sacrifice, but always keep the same amount of foliage for health.
Eventually everything will turn into a bonsai, and you will never have risked health, which, as far as an artist is concerned, means "running out of paint".
And of we ain't artin we just fartin.
