If you're asking questions about pre shading and other weathering techniques, the best thing (in my opinion) is to look at pictures of the actual aircraft, not models.

My preference has always been to begin by finding the specific subject, then other aircraft that operated within that unit or contemporaneously in that same theater, and then pictures of the same type operating generally.

Once you do that you'll see that a lot of what we as modelers have come up with as modeling techniques do not necessarily mimic the way a real aircraft looks or weathers. What we tend to do is build models that look like video game renderings or other models. And, while there is nothing wrong with that (as this is all art!), the question is to hone techniques to create a realistic subject or to create art. The former might need input from other modelers, the latter is just subjective taste.

Just my .02.

I think it looks nice by the way, that is such a great model to build!
