A few notes:

Based on the dimensions and placement of the tropical and arctic circles, this is in Plate Carree projection (The Tangent, Normal aspect of the Equidistant Cylindrical/Equirectangular). But the features don't show the appropriate distortion toward the poles, and rhumb lines and a compass rose are inappropriate for such a projection over this extent as it distorts compass bearings.

Consider what would happen if you travelled northwest and kept going northwest. (assume a magical, perfect compass) You would spiral in toward the pole but never quite reach it however many times you spiral around. If you travel "upper-left" on your map, you will eventually reach the top edge of the map, which is the north pole stretched out. This is why the Mercator projection (which does preserve compass bearings) projects the poles infinitely far from the equator and has to cut off the arctic and antarctic to fit on a finite sheet of paper (the polar regions are often covered by insets in another projection)

A universal linear scale is inappropriate for any uninterrupted map covering such a large extent regardless of projection. Again, consider that the poles are single points, the distance "along a pole" is 0, but in this projection the poles are as big as the equator. In any normal (aligned to the equator/axis) cylindrical (rectangular) projection like this, you approach infinite infinite distortion as you near the poles.

The regional map is also problematic in terms of projection. You can't just "zoom in" on a map by scaling it up. A projection suitable for a global extent isn't going to be suitable for a continent. You can sort of, vaguely pull it off if you are using Mercator (Which is why the web mapping services like Open Street Map and Google Maps use the Mercator projection) but otherwise, it doesn't work, you need a new projection for a new extent. The more zoomed in you get, the less of an issue this becomes (This is true of most of these problems). A map of a regional district and a municipality within it can share a projection just fine (I'd use UTM Zone 10 North for a general map of both the CVRD and North Cowichan for instance)

For your curved labels, it looks like you are warping the text rather than setting it on a path. You don't want to distort the individual letters; you just want them shifted and rotated. Yous should also try to adjust the letter spacing so they stretch across the area they label. (Don't just change the size or stretch it like an image, the first will make you text inconsistent, the latter will look inconsistent, and REALLY ugly)

Your terrain symbolization is also rather hard to interpret. It's a popular style in the guild, but it makes it rather hard to figure out what is a meaningful difference, and what is just decorative variation. It also makes it hard to figure out where the boundaries between terrain types are. That's acceptable for a base map that isn't really important, but if that's the case, I'd have either ditched the terrain entirely, or at least made it more subtle so the features that are important (presumably the political boundaries) is more prominent.
