Some thoughts now that we have better pictures.
Seems like they didn’t make any fat Roman soldiers, which seems quite odd considering most legionnaires in the comics are fat.
Obelix, I agree he didn’t need side articulation on his shoulders. Also, his menhir should be twice his size.
I’m surprised they didn’t make a Caesar yet.
Disappointed we’re not getting a Roman fort … yet
Lastly, a thorny issue. Someone mentioned noses. I don’t think these look like Asterix characters at all. They’re just PM characters dressed like Asterix characters. A very divisive issue among Lego collectors is faces and face sculpts for licensed characters: should they be regular lego heads ‘dressed up’, or else totally different, character-accurate molds? As a lego collector, I prefer the latter (see for eg the Lego Simpsons theme). If it’s a regular human-centred licence like Ghostbusters, I agree they should be regulat heads, but with cartoons, eh, I’m not sure a regular head is enough. Of course one downside to that would be the tooling required would drive costs up, especially with this kind of theme where there are mang characters. But as it is, Asterix for eg looks a bit ridiculous, like a child cosplaying as the Gaul.
