These are the 3-ups, and while I'm sure there is a technical reason for the bases being that thick at this stage, all I know is that the end result will be much, much thinner!
That's what I figured, since the bases as-is, by proportion, are glaringly thick. I just seem to recall other 3-ups having thinner bases. Thanks for confirming.
In any event, I like the sculpts, and it's nice to see some old-school, generic fantasy goblins in chainmail. All of this originality for the sake of originality has been killing me.
