aside from the bright blue outline, that came out pretty good. and here i am clicking on each point around a poly by hand.
Oh the outline is not actually part of the vector, it only shows when you select all the elements.
watched a few videos on youtube about this, worked at it, then refined file size down to 19.8 kb after trimming one node at a time and playing with the arrows to cover the gaps.
