Changed the color of the Green Stab horizontal bar to more of a turquoise color, as seen on one of my profiles and the NASM's Ta 152.

I'd be careful doing that. Sometimes it's a clear case of "oh, they used this color" but sometimes it's misleading.
This paint has been exposed and eroding for 60 years in open storage in the Air and Space Museum in many cases. Paint colors change, fade, degrade, can be affected by environments to become darker or lighter or shift colors (look at olive drab, so many different ways it reacts to enviroments!).
Going by a picture, which is reprinted in a book, and taken on a plane 60+ years after the fact, isn't exactly the most accurate color. The lights used to take the picture, the angle of the picture, the specularity of the paint, the quality of the film crystals, the printing process, the light you read the book under, and the way you scan the page can all subtly change the color and in the end. Also, that particular picture was taken as an artistic photo showing the grains and textures in the metal more than the colors themselves.
Still not very good lighting, here's another angle of the same:

Now, after 60 years of fading, isn't it possible it's got a greenish tint to it? The LW had many different shades of green. I say this for the sake of making you think about it. The color on the skin is your call. I just wanted to caution against dropping everything and redoing it just because a picture shows something else.

I would say the most logical is to look at the colors the LW was using on similar planes and base your jugdments on that, rather than a new picture. It's very informative when looking back on things, but does not really recreate the exact shade that was used way back then. I don't recall seeing any turquoise-ish colors on RVB before, so I'm a bit unconvinced blue is totally right just yet.
The skin looks nice overall. I like it. I would suggest making the green wave-forms on the underside leading edges shorter. They extend back pretty far as you get out to the wingtips.
