I don't mind at all! The original build wasn't even mine, so please give credit to the original author for it, if you would. You'll find the link at the top of the description for it in the "Note:" section. Honestly, this is a build I'll likely be revisiting and refitting, myself, in the near future.

Had to make a second comment for the extra bits:

I didn't make any paint changes as I felt like your paintjob for the original hull was pretty-much perfect for my purposes. I'm just wondering if you'd mind me uploading my reworked ship because it only has a few external changes and the majority of modifications are internal. I would absolutely link your creation and give credit.

I made a rework of this ship's interior and parts of its exterior several months ago. It involved the following:
Moved CIC to the bow and replacing the old CIC with a crew rec room (maybe that was swapping two rooms' positions, can't remember)
Replaced Gatling guns with retractable MCRN PDCs as this helps with the hull-shape (looks more sleek)
Removed the laser weapons as the PDCs more than suffice for anti-missile defense
Replaced two thirty-millimeter guns with two additional 75mm railguns
Replaced hydrogen thrusters with two types of Expanse-style modded engines (ions remain)
Moved crew quarters to otherwise-unused room just above the engines
Replaced M-8 missile battery with a second set of M-1 torpedoes for improved long-range fighting ability as the medium-range work is now done by four railguns
Removed most external cameras, leaving just 6 for necessary visibility
Added nameplates (is currently KATANA, DDG416)
