Gonna have to say I like the first attempt better lol.
For skin color, you should check it out using one of the other backgrounds that has in-game type lighting and see which YOU like best, since you'll be the one looking at your char more than anyone else. You can make any skin color / hairstyle / whatever else work if you take your time with it.
If I were to change anything, I might play with the mouth tail / type on the first one. To me she looks like she is forever having a bad day / always tired, or maybe it's just the neutral expression and that might not be the case in game.
Again, I think you did a pretty nice job the first time.
edit: ( comments are on the face only since that's all you're showing us lol )
