I agree with Eva, it takes anywhere from 8-9 hours or even a day or two...or for me...weeks. I'm very OCD with my sims, which I'm trying to control so I know that is why it takes me way longer to complete them than some creators. I just don't want to offer a sim that I'm not content with...it just wouldn't be fair.
She is a very pretty sim twinzie, however the face shape I don't really think favors Kiera. You sim has a slimmer face and longer chin than the actress...but you are very very close to it. Keep working on her...find more pics of Kiera and work just as hard on her profile as you do her face. I can't wait to see the final outcome!!!
*don't you just love that short cut on Kiera in that last photo?!!!! Stunning!
