So far this is a middle of the road set to me.
Some figures are excellent, like the Beholder or even the Centaur hero. Some of the commons are well done such as the Kenku Sneak, or the Dire badger.
But the scaling seems to be all over the bloody place again, just as it was with Harbinger and Dragoneye. The Undying soldier looks as if the artist started carving at the head, and ran out of room for the feet, so made an arbitrary 'cut' where the feet should be. It actually looks like it had melted, and is off scale badly in its proportions.
Then you get the mix of dwarves. In the case a friend and I bought, we ended up with all the dwarves between us, and the heads are all different in size. The Caver and the Artificer look decent in proportion and size, The Samurai isn't too bad either, but the Phalanx and other dwarf (I can't recall what it was called) seem to have these tiny heads (One being under a helmet, which would mean he'd have to be a pinhead to get that helmet on).
The halfling is tiny, but tiny to the point where no detail could possibly show up. One of the earlier sets had a Halfling ranger type that was perfect, and all others since or before then have been either too small, or too big (Such as the outrider).
Strangely, the monsters seem to have the better scaling. The 'core' races look like they are giving whoever is carving them huge problems.
