I am confused by the choice to have the Klingons look like the redesign. This is TOS era so surely they should look like TOS era Klingons, no?
In the DS9 episode “Trials and Tribble-ations” some of the cast time travel into the (legendary) TOS episode “The Trouble with Tribbles” and when asked why the Klingons from that era look different Worf only says “we don’t talk about it”
SNW takes place a number of years before that TOS episode, so perhaps we will learn what happens sometime in the future as SNW gets closer and closer to the start of TOS
