While Bezo's sentiments are harsh, I fear they may be rather accurate. Back when I was more involved in drawing SB ships I assembled all of the resources to draw the 1930s USN heavy cruisers, and I drew much of
Houston before handing it off to Bezo. The
Portlands were low on my priority list since they had neither the elegant tripods of the
Northamptons or the brawler good looks of the
New Orleans; but I can immediately point out several areas for improvement.
Colo references the drawings from Friedman's Cruisers: I have one of those three drawings here for your enlightenment. This is A.L. Raven's depiction of
Indianapolis as completed in 1932. Friedman additionally shows the refitted
Portland and the refitted
Indianapolis.
I do not appear to have scanned the other two drawings Colo references, but they show
Portland as refitted post Tassafaronga (in other words, as she looked from '43 onward). The other two drawings show
Indianapolis, which has some differences both in original construction and as refitted.
I also have this line drawing of Portland in 1945 configuration. At a glance, it looks mostly correct, but I cannot vouch for the source. I tend to be a bit... uh...
distrustful of Russian sources: in the past I've found that at least one Russian "source" decided that a forum post I'd made for a naval game constituted a proper cite. However, in this case, the drawing does not have any flaws that jump out at me. Let the buyer beware!
The bridge structure appears to be the most incorrect thing I can see at first glance: the upper decks loom outward over the turrets in haphazard fashion, and the legs of the tripod - all three legs - are too thick and do not appear to be at the correct angle. The mast rising from the top of the tripod ought to be very thin (I have my doubts that it should even be three pixels wide).
In an as-completed state, she did NOT have 20mm Oerlikons or 40mm Bofors guns installed on her bridge superstructure. I don't know when they were placed there, but I can tell you they were there by mid-1944. At a guess - and I'd urge you to confirm this with photographic evidence - they were
probably installed in her post-Tassafaronga refit.
I drew the 5"/25 guns that were used on the
Houston drawing, researching it from photographs. Someone else redrew them completely differently for the
New Orleans, with a much longer barrel which I believe to be incorrect. It is my impression that was the 5"/25 added to the parts sheet. Sounds like Bezo redrew them again more recently, though, and I trust his judgment and research skills explicitly.
From the photographic evidence I have, neither of these two cruisers had an angled funnel cap until their later refit, which saw the reconstruction of much of their aft superstructure. It appears you've drawn the aft superstructure in an as-completed fashion (1932) rather than as it was after repairs following Tassafaronga. If your goal is to show her in 1942 as at Midway,
this picture and
this picture demonstrate that she lacked the funnel cap.
Please note that, according to what photographic and illustrative evidence I have, the deck break on the
Indianapolis was located further astern than on the
Portland. This imitates what occurs in the
Northampton class. It's something to mind if you want to draw both ships.
After
Portland's refit, it appears she had a thin tripod mast installed overhead her second funnel, while the original tripod mast and the boat crane (together with the boats) were removed entirely. A radar set and numerous 20mm guns were added in their place, and two twin 40mm Bofors guns were added on the main deck. The original bridge structure was reconstructed, and the windows and balconies of the original (which you tried to draw) were erased.
You are correct in pointing out that the curve and angle of the bow is off.
The key question, as Colo asked earlier, is what date you wish to draw this ship. You said you're going for the '42 look and would then draw them as built... but the '1942 look' is fairly close to the as-built design. It was not until the end of 1942 that
Portland was rebuilt as a result of Tassafaronga. You've included elements from both pre- and post-Tassafaronga periods, and it sounds like you believe your drawing represents post-refit. In fact, it more approximately represents pre-refit, albeit with some post-refit touches like the funnel cap.
I'd highly suggest that you put together a lot more research and source drawings, then find a time period where you have good photographic evidence to support your drawing choices. Once you've figured out approximately what time periods you have the most photographs and information from, then choose that as the period to set your drawing.
In any case, I'm not an expert on these ships, so I'm just pointing out a few of the big things that jump out at me.
