this is Turian or Quarians ?

I too thought Asari and Salarian at first glance, though I can't be certain.

Also you can see Salarian posture on second one. Turians and quarians stand straight.

Agreed that the posture and general appearance is very Salarian. Ref :
Not broad enough to be Turian. Though the curve in the leg does look very dramatic even for a Salarian in the second picture.. probably just a shadowing thing.

I'll go for either Salarian or new race. Definitely not Turian (maybe).

Yeah, I agree. Left is human or Asari, and right is likely a Salarian.

LOL. Props for "Hamburgler Asari".

And for RWBY avatar.

I'd say it's a Salarian but I wouldn't expect one to be that tall. It'd be cool if they were adding variable body types to all race models, but I doubt we'd be so lucky.

The one on the right looks very definitely like a Salarian to me.

It looks like a salarian to me as well.

Looks like Salarian on the right.

Person on the right - knees are a Turian, Quarian, Salarian type - bend below, knee "sticks out" front.
However, they are very thin, which negates Turians. This is either a Quarian or Salarian.
Now, look at the knee bend again. Quarians do not possess such pronounced knee bend.
This is a Salarian.


Person on the left - humanoid in appearance - Human, Asari. However the head is elongated in an upwards behind direction, a trait that humans obviously do not possess.
Even more puzzling is - Asari have their... semi-flexible, cartilage based scalp crests that grow into shape... (hair tentacles, for the scrubs among us) relatively close to the head proper.
The person in the picture does not. Instead, their head resembles that of Javik, the Avatar of Vengeance and the Last Prothean.
Were I to compare, it looks a lot like the Divine's hat from Dragon Age.
This leads me to the conclusion that we may be looking at one of the new races.
