Hi Guys!
Thanks again for all the help!
I took a serious look at all the images I have and Joe does have it close on regards to the shadowing where the wing meets the fuselage for the angle of the sun I'm using. However, I also have another photograph that shows the same angle I already used. But it does not match the sun angle I'm using. It's rather one that is low and just about when the sun is going down within a hour from sunset. So in a way you both are right!
I too was stumped about this and it took me about an hour to find the images that gave me the confidence that what I finally did was close to what Joe is talking about. In fact, I already did my changes before I saw this post and I do know how that the shapes of objects, how their angle protrudes, etc. will determine how it affects the sun shadow and can be hard to determine.
Rikyu Wataknobe's Ki-61 shows close to what I was able to find in several photographs which I'll post later when I'm done making the current changes to the profile.
Thanks again everyone!
