Well, to be fair, they're not actual skeletons, their constructs forged from bone, yadah-yadah, infused with the animus of great heroes. while I particularly don't like the noses either, I can live with that and the grinning faces on some of them. I mean, skulls do look they are grinning in real life, these are just exaggerated a bit.
The infantry is my least favorite piece revealed so far... but I love the Necropolis Knights, the Wizard with Scythe, the catapult, and Katakros himself (though that looks like quite a journey to paint lol). The four armed guys, I like certain aspects of them, like their main bodies, and some of the weapon poses / types. I also don't like other weapon poses, and I think the four heads are just okay.
Overall, I'm liking the skelle-roid bois. If I didn't have two AoS armies I'm building currently, I'd give them a serious look. Maybe a year or two from now I'll reevaluate that.
