This is a great-looking paper model! It's fairly challenging to build and will likely take about 4-6 hours, but the end effect is very nice.
I must emphasize that this is a sci-fi tank, otherwise when you build it the scale will seem a bit strange. When compared to a 25-28mm mini this tank will look massive, but when you notice the detailing it is meant to be that way.
I'm looking forward to some of the interchangeable turrets the author is planning on making, and will likely use it for some home-brew wargames.
Definitely good value for the price.
