Moodlets Beatrice is brill! My grandad would have liked her, he kept bees for years. shorty35565 there is a whole page devoted to picture tutorials at the top of the creativity forum, here . Arisuka she does look like GaGa, it's the nose I think. AnnieBonnie she has gorgeous eyes. simtastic2 oo I like her, she looks like a real person. Is familiar actually...
Maria. She's been fun. Hot headed, which is interesting!
Holly. Wanted to make a Holly Willoughby look-a-like, but am not very good at making real people!
On lots and lots of different websites! Your best shot to find as many of them as possible is: http://mysims3blog.blogspot.com/. Mark "Hairs" in the drop-down menu to the right and that should make things a bit easier for you. I can sit and look through hairs an stuff on that blog for hours and hours!
Please do not requests Sims in these threads or go into lengthy tutorials on how to upload imagery etc. Go here for some answers: http://www.modthesims.info/showthread.php?t=337361 or PM someone on the board in the thread you are posting in. It clutters up the threads etc and makes viewing the images tiresome.
