She needs a specific time frame to be painted "to."
For one, all USN horizontal surfaces are a different color than verticals. During much of WWII, that was a dark blue color, and wooden decks were stained a version of that color. Even Measure 21, overall blue had darker decks than sides.
If this to be a post-war paint job, then she should have 96" tall shaded hull numbers, not the 36" unshaded war-time numerals. She ought to have draft markings, as well. But, this could be modified to Measure 22, which would be a good end-of-war paint scheme (and one for which reference materials abound, see: http://www.history.navy.mil/photos/images/i05000/i05560.jpg
To keep the wooden decks wooden, the choice would be as she is now, a museum ship, but, she'd have significantly different weathering, too. (Not like the weathering that occurs with 1800 hands on board, with what was probably a six-division Deck Department to keep the ship in paint and the like). Or, render her as on her maiden voyage, see the photo linked below.
The paravanes stowed just behind the breakwater ought to be a flat red, or a half-red, half-grey, with the other paravane half green-half grey. The capstans have bronze bodies, too. This is a missed oppertunity for color on otherwise bland vessels. Ought to be non-skid to protect the decks from the anchor chain, too.

She needs either a flagstaff aft, or the jackstaff folded and secured--not half-and half. The Colors flown from the aft flagstaff will want to be larger than what is flying at the mast, too.
