What has been perplexing me now for a while is that when they choose how to represent the male Shephard, they simply went with using Mark Meer, the voice actor for MaleShep, as the basis for his appearance. But when it is the FemShep representation that's the center of attention we need to have massive votes to determine which FemShep looks best, instead of just using Jennifer Hale (who is a pretty good looking woman) as the basis for her.
To me, it screams of double standard. And as many others have said, she looks far too young, to the point that she reminds me of the re-booted Lara Croft. According to Mass Effect, Commander Shephard is 27 or 29 (I can't remember which, but it can be extrapolated from reading the codex entries).
