A few small words, some positive a few negative.
So this project is by Sergio, one of the two fellows behind Tercio Creativo. Tercio ran two kickstarters for their game. The first one went beautifully, all sculpting was done already and shipped on time. The second one was a complete disaster. The caster walked away from the project but didn't straight up say so, so they wasted a year and a half cajoling him and listening to lies and prevarications and then passing these along to the backers. During this time communications with backers was abysmal, with little information and intervals of many weeks without news or progress or anything to indicate they hadn't just walked away from the mess.
Eventually they wheedled a little bit of work out of the original caster, but when it became clear he wasn't going to do much of it let alone all of it, they finally broke down and got a new caster, (incidentally, this new caster is the one who is working with Sergio for this Xtraidos project, so they are good-to-go there) and the project was finally casted and shipped. They are still shipping some of the packages now but everyone will get everything (I have received my shipment. It is missing a single minor figure, but that was a figure missing from the production run due to a casting error, so everyone is owed this figure who got it).
The Tercio figures themselves are stunningly beautiful and I love the sculpting style. It's very much in line with the more fluid, animated sculptural style of Hell Dorado, only perhaps a hair more stylized. Since Sergio is the sculptor you can be assured that the new figures will be as good.
Now, I have also bought a couple of the existing Xtraidos figures and they are both quite large and very lovely. The elf fellow with the pointing finger is no less than 39mm from the base of his feet to the tip of his hair. This works for me, as I am using larger figures for the project I got him for, but just be warned that they won't blend at all with 28mm, unless you specifically want or don't mind them being bigger fellows.
So a bit of a warning and a bit of an endorsement.
