Your new squiggly borders look much better that the old ones since I last popped in. The map feels better to look at now. I myself have no glaring major issues, but I do have alot of little issues with small details here and there. I won't burden you with them all, just some
Firstly I don't like the railway lines, they interact with the borders to much and I feel they could cause confusion during gameplay. I would suggest making something more rail like, as cairnswk done in his rail europe, afria, usa and australia. Like this image and make them some shade of grey so they stand out from the border:
Also on many of you coastal/river borders you have these secondary lines, usually in the water (i.e. around crimea) which don't look right. I know what it is your trying to do, but it doesn't work. Plus with the amount going on in this map graphically I don't really think you need these extra squiggles across the map. I would suggest removing them altogether.
