Also, it's kinda funny but I never thought I'd ever witness Geralt and the term "sad puppy eyes" used in one picture. 
Of course, it may not be that epic and groundbreaking as we describe it to someone, but in the end - it perfectly does its job, and that's what matters to me the most in scenes that partially rely on conveying emotions.
It perfectly does its job... because puppy eyes themselves are not hard to do, from animation/drawing perspective. There are plenty of those in DAI as well. I'd like to point out however the rest of the scene(s) - we don't see Ciri screaming 'noooo' and hardly see her face when she realizes one of her mentors is killed (we mostly see her being despondent via body language). We also don't really see her face much when she later sits next to the body - and the only way, really, you can tell that she's crying in the pyre scene is runny mascara.
Also - the scene where Geralt finds Ciri's lifeless body first? Based on body language his face should be a picture of pure anguish - yet we don't see it at all. It would be quite hard to pull it, TBH, since it involves more than creasing brows and squinting eyes a tad.
My point is not just to further my point about them obscuring faces - but also that cinematics/movie cadres/comic panels don't have to necessarily show faces to convey emotion.
