The reset pushbutton will be touched by human fingers, so it's worth considering ESD protection. The boot pushbutton already has some series resistance, but the reset button does not.

LGTM. It may technically breach the layout guidelines for the TVS (see section 7.4.2 of the datasheet), but it's probably not a big deal, especially with the 1k series resistors present.
