Awesome work! I can see why it took awhile to do. I have noticed the same as you when I built three Tamiya 1/32 F-15's, mostly perfect but I had to work a bit to get the best wing to fuselage fit and since I had to build them gear up the canopy and windscreen fit was an issue, they didn't conform well at the canopy bow. All three kits were the same in those areas. There has been an improvement at Tamiya over the years since then.
