First I like to say that I think that the new interface is really nice! The graphics are awesome (!) so good work guys! You did a great job!
Now the "bad" part... Some suggestions and observations of mine:
The "Jump to these coordinates button" and "Save location button" are too big - you don't need them that often and they are more distraction that way than useful. Also the "Jump to these coordinates button" is on the same place as the "Jump to current city button" in the old interface (like bottom right from the map) - that is really distracting when you first use the new interface. So to be clear these two buttons should be smaller and rectangular maybe.
The "color assignments button" seems misplaced - the position in the minimap looks weird.
The minimap is really small now and its a bit pointless to use it to gain an overview of an island because you can't fit a whole island in that window. The number for the sea even makes it more difficult and hides part of the view.
As somebody already said - the numbers and symbols for the ressources are kind of small. The population symbol is ridiculously tiny
There are scrollbars in empty lists like in the lists for recruiting/movement/trade and also in the premiumbar (if you use submenus)
The premium toolbar button still opens the list with the old list style. Same for all the information popups like if you hover over the ressources or buttons around the map.
The button for closing all windows appears now in the top right corner of the interface which I don't like that much. I think the old position was better.
I would therefore suggest a small change of the buttons around the minimap. I would try to fit the buttons for color "assignment", "save location" and "jump to these coordinates" in one line together with the box of the coordinates (make them rectangular and they will fit) under the minimap. Then I would reposition the number of the sea in the top part of the minimap instead of the left part.
