I like them a lot, expecially the wizard- which parts did you use?

I'm almost convinced to try to copy it...
Would only have shortened the "skirt" pieces a bit.
The barbarian is great, too, probably even more awesome than the wizard - I am just a bit less impressed, but only because I already knew this concept from Ampersand. You seem to have used another head than him - where did you get it? Or is it just your painting style that makes it look so different?
The others are nice, too, expecially the paintjob. When I place critics here, please note that this is only to give a more detailed opinion - the overall impression is definitely great.
You may have realized that the dwarf appears somehow "weird" to many people. I would also say he's a bit skinny, and the helmet looks too "medieval realistic" - would rather fit a human knight than a fantasy creature like a dwarf. The "brain part" of his skull looks a bit too small when compared to his face. But this points put aside, I like the model. Most of all, he has real legs, as opposed to most GW and other mainstream dwarfes, whose oversized feet seem to grow directly from their belly. He holds his axe in a nice dynamic way, not resting at his side, and also not "cought in mid acton", but ready to strike.
Skeletons:
Too much Tomb king-ish for my taste. They look like the old GW skeletons (which they probably are), which is of course true to the original HQ style, but then again, why replace the originals if not with better models. The new Vampire Counts skeletons by GW are much more detailed and natural, let alone the ones of other companies like Wargames Factory.
Fimir:
Well, those are obviousely the originals, but the weapon mod and the paintshops are really nice. Besides, I always thought the HQ Fimir were the best GW ever did.
Orcs:
I like how the new minis add detail, dyniamics and variance. I only would have liked the heads more resembling the HQ originals, not the new GW look (the jawbones should protrude out of the face, not downwards). For that reason I like the left two ones on the lower picture most.
Gargoyle:
Wow, just wow. Where did you get this mini? The painting is a bit monochrome, if anything.
Mummies:
Very, very well done.
Chaos Warriors:
I like them, but find the fur capes a bit annoying. Again, this is a GW fasion of the last few years, that CWs al2ays wear this furs.
