I got the Dragon one last year. I like the concept a lot as you basically have a full face in one palette and the powders are all quite subtle and buildable. It leans a little bit warm toned for me though so I bought the four pan that came out a couple of months ago which is more cool toned and I also used that Cult Beauty £50 code glitch from May to buy a full size bronzer that leans more cool.
Upshot is I have more than enough Hourglass to last a few years so I'll have to keep a grip on my FOMO for the next release because realistically nobody needs multiple of the holiday palettes. The colours get recycled a lot too so once you own a few powders from Hourglass there's a decent chance the new palettes will dupe some of what you already own.
On the subject of being warm toned it does seem to be a common mention/complaint that the 6 pan palettes lean warm every year. They do 3 palettes to cover fair, medium and dark skin but they are still all warm. I did think the Deer palette might look as though they addressed that a little bit but until influencers start receiving them as PR and doing swatches it's hard to tell.
