I am actually a member of your group Le Clan. But I need to type all the things in English instead of French so as to make sure that all people understand.
I like plain geography map very much, and I would like to give you some suggestions for this map. Firstly I suggest changing the title of this map from Switzerland to Swiss Cities. If you name it Switzerland, people might have an interpretation that the map is made up of the states in Switzerland. If you change it to Swiss Cities, people will know immediately that the lands in this map are points, but not areas.
Secondly, I know that you need the red colour and the white colour in this map because they are the main colours of the Swiss national flag. However I think that using the red colour to represent non-playable area is not very appropriate. if you interchange the red and the white, the effect may be much better. The main reason to explain this is that the red in this map is so sharp that it will distract people's attention from the main area.
Thirdly, I do not think the foreign cities in this map are really needed unless you find something that they are related to Switzerland. If you think that you need some foreign cities to make the map become more interesting, I suggest adding some cities that are closer to Switzerland. For example Feldkirch in Austria, Lindau in Germany (Munchen is too far away), Genoa in Italy (Milan is also too far away), etc. Also, Lyon can be cut firstly because its location is wrong here, and it has no relationship with Switzerland.
Fourthly, it is about the gameplay of this map. I highly appreciate the bonus because it is very interesting indeed. However I do not agree with +7 and +9 for A1 Highway and A2 Highway repectively. This is too much for a map with such number of lands! Also, I do not agree +5 for 7 German Speakers because they are very near to each other, so it is very easy to hold 7.
In conclusion this is a very decent map, and it has potential! I hope that my suggestions and ideas are useful to you.
