The trees look like they have had much more lower live material removed in the past.
Most definitely was there a lot more removed in the past as you could tell from the pix. I think the earlier trimmings were to remove the branches that were on the house and windows (environment). I'd guess the opposite side trimmings were for a "balanced" look.
Many of the spots I did prune had been pruned before.
The trees overall are very healthy looking. Nice root flares, no girdling, bark loss, boring holes, etc. My observations are only visual and very basic. I pick the tree care stuff up slowly. Alot of black magic in that science that I have not spent time with.
Overall I'm happy with what I did. Clean cuts where I pruned. I left good collars. No nicks in the tree. No spikes.
