I agree the Ki-61-II is the most beautiful single engine fighter aircraft of WWII, particularly the "bubbletop" version.
Twin engine would be more crowded for best looks, but the same manufacturer's Kawasaki Ki-45 is up there as well for twins.
I wonder if the curved left wing (from the Hasegawa 1/48th kit) is fixed on these moulds? It seems likely given the all new sprue:

It may seem like a very easy problem to fix by bending: Don't believe it for a minute... Bending will inevitably cause a dimple on the thin top side plastic. Also, the Hasegawa wings don't taper continuously in two straight top/bottom lines from root to tip (as they should): The bottoms are moulded in a strange lateral concave curve, especially the left wing, so the outer half of the wings are almost paralell top/bottom, rather than tapering to a fine sharp wingtip; any attempt to bend the outer wings hugely exaggerates the fact the wings are almost straight on top but curved on the bottom... I got close to fixing it but it took several kits, and in the end the lack of continuous taper was just too obvious...
Great new subject to see! The exhausts should have many substitutes, so that doesn't seem to be a big deal.
