I think your sim looks quite unique but it could use some work, though in your case I would try to shape the eyes and the facial shape some more since it's quite close to the original ts3's template. (sorry for my late reply! >.<) I agree with Jo. if your sim is pale, wearing white clothes and has pale hair you might want to try a medium grey/beige background. Your photos are good except for the white back ground, it's too bright. Photos need to be no smaller than 800 by 600, taken in game with good lighting with the face shot done straight on with the sim having a neutral expression. I hope that helps with understanding the face sculpting requirements? If you remove all CC and people go 'that is face template 1, 2, whatever' Then you know your sim isn't sculpted enough. I disagree that it is difficult to get a sim uploaded here, it must simply not be a recognizable template face, which means it does take some work. To be worthy of upload a sim must not be something that anyone could make in five minutes. I don't moderate sims 3 sims so I can't pick the face templates which is why I am asking which one you started her on.

She must look significantly different from the base face that you started her from. What face template did you start her out on? The most important thing is face sculpt. I would suggest taking a few more pictures, in the same category as post#11, but looking more like the third pic in post#7.

Remember, you can include other fun poses as well, but the mods are mainly considering the required facial pictures. This may seem really picky to you, and it is, but as I said before, it is hard to get a sim approved and you want your pics as close to perfect as possible, so the sim really shines. Also, it is better if all the pics are taken with the same neutral background, so the focus is on the sim.

The camera angle is down, not straight ahead.

You pics in post #11 do not have the sim looking straight into the camera. The sim is looking straight ahead, with a neutral expression, and the lighting is good- bright but not so bright that the sim is washed out. In post #7, I think the third picture is what they are looking for. I think she is unique, but I am not a moderator. You really want to take the time to submit great screenshots, since that is the only way the moderators have to judge the sim. Honestly, it is hard to get a sim approved here.
