A few things:
1. The airplane crane you're using on the first version is actually the same "type" as the one on the second ship - it's just a poorly-produced, out of scale version that was drawn in 2008. The differences between the two should show you how far the style has come...
2. You are using the later-era "cockpit" Mk.37 directors on the first drawing (impossible as the director didn't exist in this format until 1944 or so). I would suggest using the early "taper back" directors on both drawings, with no Mk.3 slewing sight visible on the first drawing's directors.
3. You have used an old version of the Mk.38 director on the first drawing. I would just pull the directors from the 1941 versions of BB-55 or BB-56.
4. If you are using the "modified" Measure 2 as drawn on my 1941 BB-55 in the second drawing, the light grey was painted from the tops of the stacks and up only. But it's very possible that Texas has its own camouflage schemes, so it doesn't really matter.
5. You've used the old 5"/38 twins. They are ugly and should be removed ASAP...
6. Interesting use of the Alaska crane.
I might go with the North Carolina crane instead. It's a bit older of a design and more in keeping with the time period.
7. Conning tower viewing slits are not glazed - so no reason to show them as blue. I prefer to use a dark grey.
