Daphne Groeneveld is most likely Sera's facemodel, so i'd say she looks like her more. 
You just can't go wrong with the eyes, nose, mouth.
Maybe it's just the 14 kilos of make-up on her face, but I can't say I'm fond of those images. If she is Sera's face model, then I prefer the in-game render. Sera's face is endearing, in an abstract, indescribable manner.
The only thing "weird" about Sera I would say, is her nose (and even then I know a handful of people with noses like hers, and several of them are attractive women).
If any elf has a weird face, it's Solas and his butt-chin.
