Just wanted to point out, this isn't technically Mass Effect fan art so much as it is fan art of *crystalcosfx and all of her works (one of the most recent being her cosplay of Commander [German] Shepard.)
It feels like a month or two since I started this, with a lot of my schedule being eaten up by some recent developments where I live, I checked to be sure...turns out it's been 25 days from the head until the devArt account.
Any who, I think all of you will be most surprised to see the catalogue of Ms. Graziano and friends' costumes. Simply put, they are most excellent and in my opinion, a grade above the usual costumes one sees at a convention.
Okay, so I'm not really so black in white on that topic, as I feel that a fan in a costume makes the cosplay so much more than a booth babe/dude/non-fan in a costume as they know a bit more of how the character acts/poses/is. And in this case, fangirls and fanboys rejoice! *crystalcosfx is one such cosplayer, adding her talent to her fandom to bring some excellent works.
And yes, I did say fangirls, she has also cosplayed Old Snake and sexy Raiden (as it's a name for it I prefer to refer). Now you can have your beefcake and your cheesecake.
So in-a-most-stereotypical-anime-fashion, GO! Seek out her great works~! Venture through her gallery, and be amazed. And you'll also probably end up with a Firefall beta key if you're awesome, as they do sponsor her.
