The Balaur is also the only one with accurate wing feathers as far as I can see.

Still, they're all gorgeously painted even if not entirely accurate.

Actually I believe it's just the angle and the balaur's fingers do not have primaries. Fortunately, this is corrected on the actual models.

I just liked the paintings because they looked pretty. I didn't mean to start a discussion about how accurate they are :P

They're wonderful paintings, though I'm not particularly fond of reconstructions that exactly mimic the patterns of extant species :P

The only ones that exactly mimic a modern bird as far as I can see are the Lammergeier Velociraptor and Egyptian vulture Tsaagan, the others have some similiarites in their plumage to extant species but are also different enough to not be the same thing IMO.

I'm not sure what species they all are, but besides the ones you mentioned the third one is a Scrub jay, the fifth an Ornate hawk-eagle and the last a Northern goshawk, all pretty clearly recognizeable :P The only one I'm not certain about is the fourth (Balaur I think).

Most of these are really distracting due to the naked fingers and aberrant colours. I'd complain about the unfuzzy feet, but other theropod groups have offered enough reasons to give that a pass.
How are those colors aberrant? apart from the blue one (which isn't even that jarring) most seem to blend in very well with their enviroment, just look at their surroundings.

Also why are naked feet and fingers a problem, you do realize they also appear in many maniraptorans including birds right?

That's not an accurate reconstruction:

As far as we know, ALL coelurosaurs - and possibly most theropods, period - had their fingers incorporated into the wing.

They are all based on living birds. If you go to kickstarter webpage you can see that the ones that were unlocked recently are planned to be based on living birds. And the Balaur looks like a pigeon to me :P

Some theropods didn't have wings, though (at least AFAIK, maybe there's some new development on this I'm not aware of).

Pretty well up for debate actually. Concavenator possibly having wings outside of coelurosaurs would indicate they predate coelurosaurs as a whole and that every member at least used to have them. Some groups are considered fairly likely to have lost them, namely Therizinosaurs, large Ornithomimids, and early Tyrannosaurids as they used their claws for grasping.

Even if you're still skeptical of Concavenators wings, that just leaves a bigger unknown instead.

Eumaniraptoran wing structure however, is not an unknown, not by any means. Anyone who's ever forgotten to wear hand protection in strong wind knows exactly why bare/scaled fingers that offer no evolutionary advantage is such an unlikely happening. Digits have a lot of blood circulation (don't quote me on this but I would think feathers, let alone wing feathers with their stronger shafts, would increase blood flow further) so it makes sense to cover them in feathers which can both insulate and disperse heat. Eumaniraptorans didn't use their hands to grasp prey, thus there is no reason to require the digits be mobile as opposed to protected from the elements.

Heliosphoros already pointed out the truth of the hoatzin chick, but as a note on feet it's pretty much unknown too. It's unlikely that dinosaurs that did a great deal of running (as the feathers would become damaged), or that used their feet to hunt (as the toes need to be mobile) would have feathered feet or toes. Owls have feathered feet, these feathers serve both as insulation and as short-range sensory organs but they don't completely cover the birds feet, rather they cover an undercoating of scales. It's possible a Dromaeosaur could have had something similar, but it's a pretty exclusive adaptation to helping owls hunt in deep snow so I doubt it.

It's hard to judge animals like Balaur or Compsognathus that would have behaved similarly to flightless gamebirds since a birds scaled feet also serve to make perching easier. Balaur is the only one of these I wouldn't be surprised to learn had feathered feet.

I don't think therizinosaurs or the like would necessarily have lost wings. If I'm not mistaken Beipiaosaurus didn't.

Mammals and pterosaurs do/did well with fuzzy feet, and given the presence of feathers on Anchiornis and most fully complete dromaeosaurs it's likely several dinosaurs had fuzzy feet as well.

Rat snake is love... Rat snake is life

Problem is there are only a few ground based birds today to have fuzzy feet and most of them are those that live either in super cold or super dry environment... Not going into fossil evidence or anything...

Well, both Anchiornis and Sinornithosaurus lived in fairly mild environments, and were mostly terrestrial (they couldn't glide well, though the possibility of powered flight shouldn't be dismissed).

Well, anyways:

Though it was probably designed with a marsupial identity in mind, this Groeberia depiction should still be decent, since it doesn't particularly resemble the shrew-opossums it was once thought to be related to, and seems to hint at the sprawling gait of gondwanatherians.

Also new Groeberiidae page on english Wikipedia. Up-date the spanish and italian pages if you can.
