I have an art background and made a point of seeing his work in person. Amazing stuff with so much imagination. No one had ever done anything quite like it before.
There are often paintings or stone carvings in cathedrals that have scenes of the Last Judgement or other scenes of the blessed or the damned and without fail, the damned are always more interesting. They are so creative in what happens to the fallen but Bosch took it a step further and really, truly made the others, such as the birth of Eve (left side of painting) super interesting too. Adam looks at Eve and kind of says to God, "That's for me!?!"
That said, I look at these figurines as kind of cheap. Yes, later generations can take the work and run with it but this just seems lost without the context of the painting. But if others like it, so be it, and enjoy but make sure to study the original in detail to really understand what you're buying.
That link to the interactive website is an excellent place to start and have in the past given it to friends and family.
(one last note: In the lower right of Michelangelo's last judgement, there is a figure with donkey's ears getting his privates bitten by a snake. That's is Biagio de Cesena, one of the pope's guys, who annoyed Michelangelo. Everyone recognized Cesena and he complained to the pope. Il Papa told him to get over it. Link here:
