You could paint up the Tamiya, and judging by your skill, it would be fantastic, but it could never hold a candle to this masterful work you have shared with us. It is unbelievable. Honestly, I love civilian tracked vehicles, and having been a fan of this particular genre, I have never seen anything, anywhere, that even comes close to what you have created. it is your embellishments that have made this model "POP"!
As "Oliver Twist" said, in the Charless Dickens classic,
