Interesting ship, though a bit monotone for my taste. The two 30mm mounts being placed on top of each other down to the pixel on the sides of the conning tower, for example, and the way the railing beginns and ends exactly at the same places around them. So yeah, I think that's something you could work on.
I do, however, really like your turrets and gun mounts, especially the 5" guns.
Which leads me to thinking... would the different nations of Tamriel use the same measuring systems as us? It would make sense if they didn't. (I know, I think too much about these things. This is just me pondering, I'm not saying you should invent a new measurement system)
Minor nitpick for the story though:
The class was also armed with four quad torpedo launchers in an arrangement similar to the Japanese cruisers
As an amateur author, I can't help feeling that you should not compare ships from a separate universe with RL ships in the backstory. It really breakes the mood. I'd make note of inspiration and such in the "designer's notes" I'd place under the drawing.
