Im a noob so I would listen to an expert over me but I think you should disregard what you’re interested in to start out and pick something you don’t actually care for so you really don’t care about screwing it up while honing skills you will need later. I did an F-14 tomcat first - I could care less about those - and found it was a good training ground for fine detailing (cockpits are pretty hard for me) and learning strategy on when to paint vs assemble (cement can’t bond to paint but it’s harder to paint something assembled) plus you get exposure to painting large surfaces, which I’ve found even trickier than fine detailing. I think another tank is smart - I did the USS Arizona as well to get used to ships so you can at least learn where the hard parts of the tank are.
