I liked the modified version that to177 posted. Particularly with the smaller stabs that's my main problem with the Yamato. Otherwise its not bad at all. Also, maybe the bottoms of the legs MAY be a bit too big like "Bell Bottoms" giving it the back heavy look that the Yamato has.
As for the color I used Tamiya German Grey.....it's the darkest grey I've seen out there. The slightly lighter panels are MM Euro Grey. The only black on my model are the "shins" of the legs, which are the tops of the engines, and the engine fan cover, that's it.
