Well done on your repair.
there is still alot of corrosion that still needs to be removed from the tracks.
the areas that have lost the green screening and are grey, plus the areas with the bubbled green screening have still got corrosion and will eventually be eaten away if it is not removed.
I have highlighted the areas that still need attention for long term reliability. hope you find these pointers helpful and i hope my comments haven't offended you
when i do my acid repairs I spray the board with clear lacquer that can be soldered through before installing the components so the copper under the components and i.c sockets are not left exposed.
I then clear lacquer again once all the components have been fitted
