Seems like a good job. I appreciate having Scavenius af the foreign minister rather than the facist demagoue.
A bit of spelling.
"Det Danske Stålvalseværket" Is a bit wronly worded.
It should either be
Det Danske Stålvalseværk
Or if you want to keep "Stålvalseværket"
it should be named something like
"Stålvalseværket i Danmark"
Also your naming of Denmark is a bit inconsistant, while you have Nørrejylland and Sønderjylland both with "ø" you have chosen to name Sjaelland without the Æ, while i might be a miss of any historical source stating that Sjælland is spelled without Æ at the time of WW2, i don't think this is the case.
Further on "Nørrejylland" while the term indeed mostly refer to the region you've designated, it would more aligned with how it's used to just call it "Jylland" while keeping the "Sønderjylland"
With regard to your focus "Sign the Kanslergadeforlig"
It would be more appropiate to call it "Sign Kanslergadeforliget" Also Kanslergadeforliget was signed in 1933, so pehaps renaming the focus to Continue Kanslergadeforliget, might be more appropiate.
Bondepartiet as representing the non-aligned i a bid odd in my opinion, the party was insignificant, but pehaps your choice might be the best moddeling of it after all.
The straights should argueably be split into two parts.
Historically prior to WW2 the danish straigts was where you blocked fleets off, however, Germany constructed massive guns on both the danish coast of Northern Jutland and on the South Coast of Norway to effectially create a new straight that was blocked off.
Also i really hope you touch on the fact that Germany expected an Allied landing in Denmark, and thus Denmark had a massive share of the atlantic wall build along the coast of Jutland.
Lastly, you should add a port in Esbjerg
