Thanks fellas!
Good suggestions all! I'll wait until I get all the rivets in before tackling the shading more. The rivets are somewhat difficult right now as not many photographs exist of the real Ki-612-II's Supposedly only a hand full were made, but again I'm finding the exact figure is different depending on your sources.
I have done more, but will post later when I get several things done first.
Again, thanks fellas!
