tl;dr
I have been a bit concerned with Mecyna lately, and I thought of proposing new ideas for this blue nation, which is now full of random, jumbled up motorways and too many cities cramped up that does not really make sense.
Many of the motorways/trunk roads and the cities need to be downgraded. Some can be removed as well, such as this motorway that stretches across Glotqua to the other side near Gilagonas via Bellefontaine. Mislabelled settlements as cities can be downgraded to town or village or even a hamlet. This so-called city, for example, can just be a village, likewise for this. Other towns like here can also be further downgraded as well.
As for geography, it looks fine but I feel that the desert plains in neighbouring Elhadia can be extended to the north (which looks like a plain at the moment). The forests could be better drawn like Gobrassanya, but it is not like there are any pro-mappers free to do that. But the detailing can be done much later, or otherwise, forget it if some newbie is going to come and wreck the forests with more motorways. The central area (around the canal) can be wetlands and swamps, while the south can be mountainous as well.
I have some ideas for the culture for the nation as well (read: a bit of history may be involved). So far, the nation is meant to be Florescentian (Portuguese), Castellan (Spanish) and Ingerish influenced. I have my doubts on Iondalban having arrived because it is very far away from Mecyna unless it has already made other deals in other neighbouring nations. Iondalban does not look mapped at all, so why can it be a coloniser?
There has been a slight taboo of having an Ingerish colony, so I thought of possibly Aloran colonisation since it has also made such efforts in nearby Central Archanta. Any other proposed Ingerish-like coloniser is possible. Nothing much to say on Castellan arrival; as stated in the article, it has made efforts to build the canal and there are already former Castellan colonies.
About the local culture, since Elhadia and Central Archanta are African influenced, I thought of proposing it to be northeastern African culture, like Somalian and/or Ethiopian culture (there can be others). Thoughts on this though? Note: the culture does not need to affect the status of the country, which is said to be prosperous. Why not have a version of a rich and uncorrupted Somalia then?
Before ending off, the flag needs a slight change (no offence to whoever created it). It needs to be in proportion first. I am unsure about the flag's meaning though, is the red circle meant to represent the nation, with the orange the land and the blue the sea?
