Dick,
That really looks good.
I think the Ki 83 is one of the three best looking twins of all time and you have certainly captured its looks with even a profile. I am looking forward to seeing it in October. (What are the other two? you ask. My list includes this Ki 83, the deHavilland Hornet/Sea Hornet and the Grumman F7F Tigercat. The Westland Whirlwind almost makes the list but is more "interesting" than it is a really attractive looking aircraft.)
What you have accomplished with this is one of the reasons that I think this multi-engine profile scale idea of Mike Keville will receive increased interest.
To go along with What Chuck Snyder asked above, I will also be interested in the documentation when you bring it to Tucson in October. There are a few decent 3-views of this and there is a book on experimental Japanese fighters that has a surprising amount of detail in it. There is also a 1/72 plastic kit that builds into a decent looking model.
Keith
