You have been reported. Just because you don't like it doesn't mean you should keep hating on it. How would you feel if I put comments like that on your art? deviantArt is a place to spread the love, not hate.
I personally like Bioware's version but.. i guess they could have more with the face and if they were too do more then it should like this and this is the only other un masked version of Tali i like sooo yeah i think this works well just.. idk i guess i can believe this. They are suppose to have clear eyes and judging by how they have ancient writing in a script style and markings over their buildings and ships, i could see them having markings like tattoos on their faces. Speptical about the dot markings but.. not to sound rascist but the Quarians were largely based off of Mid Eastern style at least Mid Eastern style clothing and outfits so i suppose i can see that and think this fits best
the colour of her face is not blue, blue is given by the light of the stars, same as the other side of her face. I don't see anything of "Avatar" in this piece, why? because the Na'vi are different, big eyes, small nose, pointy ears...I believe that this [link] piece has more of your description than this one.
