What can I say, this is just stunning work! I don't know how much time this took, but to me it screams dedication and love for doing things.
I also adore how perfectly the roof fits around the top of the windshield/A-pillar area. And as I understand it from the pics, the doors don't open, but you made it look like there are shut-lines visible in the interior? Very cool.
I am just returning to modelling after many, many years and things like this are inevitably a form of catalyst to actually do something 'more heavy', so to speak. Well, only that these days I also need glasses for the stuff I like doing the most - details.
Those many years ago I used enamels, but I just prefer acrylics today, partly because I don't have a dedicated well ventilated room and partly because it's also on one hand perhaps a bit more difficult do some things (like wash), but on the other I don't need to wait several hours to continue. But since you used acrylics in the tutorial, did you use it for the chrome parts, e.g. around the windshield? I don't know of any good chrom-like paints that would also be useable with a brush. I have Tamiya's 'chrome silver', but even though it can be used for some things, it's far from ideal. Revell's chrom spray is quite good, but expensive and not for a brush.
Anyway. Awesome work and pics, thanks!
