Lancelot, sorry it taken time to get this posted, just a tad busy, but here are some thoughts for you.
Reduce the texture on the mini map. It is causing the names to become harder to read.
Impassables, this is almost hidden from view. Like the troop text, might as well put this into the grey box legend and lump all the rules into one place.
Territ names, slightly darker and bigger if you have room. Not to much but some.
You have some highlights all over the map. Whilst nice, they are too strong. Reduce.
Meurthe et Moselle name is going over the territ lines. Move the name south some so as it does not. Go around the other names and spot ones like Belfort. This goes onto the line but has room to be moved into the territ. Some of the other names could do with a move as well. Corse de Sud name is hard to read in the sea.
Bridges, fill the bridges up with a colour. Now they are nice apart from the one between Morbihan and Loire.
Rivers to sea, blend the colours more.
And with the sea, how about some gradient so it is not a flat colour. I remember you had the map effect early on. Try to get that back or if not, try to create the same effect with what you have.
Mountains, I like the ones you have in the south the most. The rest are just overboard. Too bright and garish. But most of all, you need to tone them down some. Either way, I think you have two option, 1,try to replicate what you have but toned down a lot but I was looking at Africa 2 lately and like the sand dunes on that. They look very similar to the mountains on the right (proper map jpeg) and might be the best thing. What are your thoughts on this? Would you be willing to try (the Africa 2 sand dunes) the new mountains to see how they look?
Lastly, name change to France 2.1 - This is really a personal request as I love World 2.1 and USA 2.1.
I know this might seem a lot but it really is just the last few things to tidy up. I love this map and cannot wait to play it. Thankfully, you are probably 99.9% their.
Wrong us, shall we not revenge?
