Overall what you're skinning is not that different from the general "standard" paint scheme of the time. The only differences being the lower camo demarcation (possibly just mottling, or possibly solid colors, or a combination of both) down the sides. I would say (but it goes without saying, hehe) to look at the basic G-14 camos for references as well, if this specific one isn't available.
Then fill in the details, like the over-spray area under the 8. For example, your skins has it as a "loop" of color that extends downward. To me, looking at the decal sheet low-res profile, and looking at the ARC buildup and the DekkeR profile, I would say you might have it wrong there. It looks more like it was a larger over-painted area that was "cut off" at the panel line (perhaps a replacement tail was attached?). Mind you, this is just working with what we've got in this thread. If that is the case, I might expect the over-spray area to be a different shade or entirely different color than the surrounding camo colors. If gray, it would be a fresher application, more hastily or thickly applied than the underlying. If green or some shade of brown, I would expect it to stand out more.
I'm not totally sure, but I also think the RVB in your screenshots is too thin. It seems like it ought to be 50% wider at the outer edges. This is generally from looking at late-war RVB and noticing they are much thicker ("wider"?) than prior theater bands.
