Another fine board. You have greatly improved the graphics in this one. The borders are far cleaner than in your previous Finland map. However, they could still be cleaned up a bit. If you are using Inklight to create your SVGs, you can switch to the node-view mode and manually drag the nodes closer together where there are gaps between them, such as at the intersections of Pori, Nakkila and Ulvila. Doubtless more experienced mapmakers than I know better techniques, so definitely ask for advice from everyone you can.
As far as game mechanics, this board is top-notch. The only thing I would change is perhaps to include Somero in Eastern Finland Proper, as it appears to be the only region that is not part of a superbonus.
