To confirm your suspicion, they did change her face to look quite different in-game which is a pity because you did a really great job here. I'm not a fan of how it came out in-game, and I wish they had kept your original version. Thanks for posting it here to share with everyone!
Wow bro your this pic is quite interesting and quite complex with those weird electric like Lights going around the character. you have done the anatomy well and it is very pleasing to the eye. Oh I see that its Ice(frost) and Lightning which is really cook this gal here looks quite powerful in her stance good job and I just love it ^_^
