Clean map, tastefully done. Here's what I like:
Everything in the design hierarchy has been carefully selected and placed -- unlike the usual "data dump" approach used so often these days (find data, dump it, then find a way to make it "pretty", including lots of haloes around text).
Lots of redrawing of linework -- almost inevitable at this scale, and given the multiple data sources (as you noted).
The relief is understated. It does what it's supposed to do, and no more.
Minimalist use of lines. For example, no strokes for water bodies; white outlines for states. No unnecessary base map detail. This approach keeps everything clean and reduces "eye noise".
What I would change:
Ditto to the others' comments on the tiny townstamps -- they definitely need to be bigger.
You could restyle the shortlines as purple, and the mainlines as a lighter and/or finer purple line -- something like the way you did the roads on your Truth or Consequences map in the Cartography Design Annual #1. The two kinds of rail lines would then retain their visual association through colour. BTW, I aggressively avoid use of black for linework (except of B&W maps) almost as much as you avoid letterspacing lower case!
The water names outside WA are difficult to read. The trick is to fix this without making them too dominant within the state. Maybe add a little magenta to the text colour? I know I can trust you not to use haloes.
Have you thought of labeling the newly-named Salish Sea? It's pretty recent, and completely official. The only widely-distributed maps I've noticed that include it are from
Canadian Geographic.
I agree about the remark on the orientation of graphic elements on the left side (title, scale, etc). I know there's some sort of graphic design "rule" about not mixing centred with flush left, but none of those rules are absolute. Still, it does look a little hodge-podge.
And yes, the international boundary does need to be acknowledged somehow.
Looking forward to the next version!
