Much better pics especially the close ups.
I agree with the others above that she is very pretty and a good 2nd sim.
Sims aren't easy to create and get to make realistic. If you don't have the full list of sliders - I highly suggest you get them. They make CAS much easier and gives you much more range. I'll include links below.
It's hard to tell from the pics but do you use 3rd party skin and eyes? If it was my sim, I would use different eyes - there are several excellent variations on MTS http://www.modthesims.info/browse.php?f=375&showType=1&gs=2 . And different skin - I always suggest Navetsea' skins http://navetsea.blogspot.com/p/the-sims-3-skin-mods.html .
The skin, IMO, makes or breaks a sim. You can create a stunning sim but if the skin is not attractive - the entire sim doesn't look right.
I would give her cheek bones, nose, chin and facial structure more definition - don't just rely on the make-up to define her cheek bones.
Make-up and clothes, to me, are just cosmetic and, most times, will be changed as soon as someone downloads the sim. I like most of the clothes and make-up you used but they aren't what I look at when I'm deciding to download a sim. . . . . . . . unless it's some really cool outfit or whatever I've never seen. I try to make the sim itself look as realistic as I can so no matter what clothes or make-up someone uses, the sim will still look 'real'. A lot of people I've seen use photoshop or similar program to make their sim look better - don't get in to that practice. The skill is in making the sim -not photoshopping it. Most of those sims look like crap when you download them.
I think you are definitely on the right track to learning to make excellent sims. There is always room to improve but this sim is an excellent 2nd sim.
