It's personally quite well done.
Saint Joan Arc, I've heard her before.
I thought it came from, Yu-gi-oh! when I saw this saint card before.
But again, probably I am wrong.
But you deserve a 4/5.
Dude, try and do this right if you are gunna make her... Research on her before you go about making her because for one the armor should not have color, Her armor was said to be white. so you should remove the shoulder color, the brown in the armor, and the Skirt around the armor should be red and if possible red with some black markings in it, the blade is okay but i feel that is should be smaller for the fact that it was much smaller and it looks far to big for the Model and last her hair, she ended up cutting it so you should make it shorter if possible, so I have to say its a 1/10... sorry for being harsh but I recently learned about her in High School so, I have a better picture of what she should look like.... oh and you should also add a crest on the end of the sword with a cross like something in this pic
And yes, it's easy to say the details but it's hard in doing it.
Why don't you do it yourself so this modeller can learn from you? Not trying to be insulting so sorry if you feel offended.
Anyway, adding too much details means more polies, more polies means larger size file, larger size file may lead to disapproval.
Warcraft is kinda backward 3D game compared to those games like Unreal Tournament or Halo, so we will have to suffice with this.
