Other than the nacelles being angular, none of those DSC ships looks like the other. And most of them look like ships that would be operating post-TUC. SNW is starting to get it right, though.
Yeah, the more that SNW gives us their take on TOS ships, the more unimpressed I am of DSC S1. They basically put the equivalent of 21st century Navy designs in a war of 1812 movie.
In my head canon, I'll assume Traveler-Wesley farted and went back later to fix the aesthetics.
