The work and effort you have put into that P-51 is absolutely stellar Toshi. As others have mentioned, your skills and techniques are improving immensely. I'm just glad that not only are you enjoying yourself but, that you are taking the time to share your build and progress with us. You've got to love this hobby when it puts you in a place where time has no meaning. That is unless one has to be to work bright and early in the morning. Then it's, well, not too cool. Lol.
I so want to get the Tamiya 1/32 F4U-1A Corsair kit. I love the Corsair and that kit is simply choice. But unfortunately I'd have no idea where to put it when done. And more importantly, although my wife is hugely supportive of my modeling, I would likely get the stink eye from hell when she found how much I shelled out for one of those beauties. I look forward to when you get started on that kit.
Keep bringing us the good stuff Toshi!
