The first picture you posted has:
This results in an 0.2mm clearance between the NPTH and copper. From what I remember it is bad practice to drill NPTH though copper. I am not exactly sure about the details, but I guess it is to avoid burrs on the copper.
Recently I looked up a video about PCB drilling, and they put a sheet of aluminum over the PCB before the drilling starts: https://www.youtube.com/watch?v=W130X0kSzYI&t=30s This is also to prevent the copper from being pushed upwards and and forming burrs.
Another improvement is to move the pad number for pad 9 and make it smaller, this can be done with a “number box”. See the post below for more details.
