Zoker: that looks really great !! My only suggestion is to make the ears a tiny bit bigger and rounder, since lion ears aren't quite so perky.
~MapleFeather~: looking pretty good so far :> I'd suggest adding a bit more variation in the thicknesses of his abdomen, since it wouldn't be quite so even all the way down. Maybe curve his back slightly and make his ribcage bigger? You might also want to size up his legs, too.
Veins of Opal: that looks really awesome !! Almost perfect, I think. But I suggest dropping his waist and belly button, since they're located closer to the hips. I'd also suggest widening his abdomen a bit, too, since it's kind of thin in comparison to the size of his shoulders and hips.
Stonefly: those are looking great c: my only suggestion is to increase your line variation a bit, maybe so it's bolder in the eyelashes and eyebrows but more subtle on the creases and eyelids.
Corgie: omg that looks awesome ;v; I really don't have anything to say on anatomy tbh. I think her left arm is ok, too, since the edge would be hidden behind her back in 3/4 view. I'd suggest maybe increasing the contrast on your shading, perhaps ??
TurtlezSoup: I think maybe you should make the shoulders come out a bit more on the front legs. The back legs look great so far though, although you could shorten the lower half, I think.
I haven't posted here in a very long time, I hope this is ok :')
