Why do most Krogan and Turians look kinda....wrong in this game?

I don't see anything wrong with the Krogans, except there are much more female around now.

For Turians, I got an impression that they become a bit thinner and have less intimidating face then the last ME..

I'm really not seeing it. If anything, I'd say they've survived the transition to Frostbite better than the other races. Including humans, which is odd, because you'd think the Frostbite engine would already have seen its fair share of humans...

The coloring on the Turian face plates is reeeeally off. The bone white face plates are so uniform in color, they look unnatural (unless that's just due to my graphics settings). Vetra looks fine though.

Thank you, that's the description I needed. Hell, Eve's face mostly hidden I could still see more facial detail/texture than Kesh FFS.

I noticed this as well. It's a little unsettling. I've also seen a few pea-green turian faces, still very uniform in color.

The Turians seem to be a bit cartoony. The colours seem to merge together on their faces and their clothing. Not sure if that might be a bug or not.

It's the turian legs that are bothering me. Their legs are bent in a very exaggerated way, much more than in the other games

The Turians and the new race (forgetting name atm) seem to stand strangely. Like their torsos are fine, but their legs are in the wrong place for their center of gravity, as if they should be constantly falling backwards or forwards (depending on which ones I'm looking at).

But this seems to be a general screw up, as everything that walks and runs seems to be off in its animation, specifically, the center of gravity of the model. When Ryder runs, their back is straight, but their legs are being lifted as if standing still, while in reality we lean toward our direction of travel when running to offset our center of gravity as we push down and away from the direction we want to go.

The running animations for other races, and even humans I guess, in MP are funky. They're like weird lurching lunges. Kinda stompy. Like everyone has really heavy shoes on and has to labour to stride.

Yeah... the little wrinkles in the mouth and eyes of characters like Mordin or Wrex, like... the skin doesn't move with the expressions, it just stretches... weird step downs in many areas.  

Or more like textures/shaders as a whole. Their face bones look almost... plush at times.
