Use Bodyshop.
It has WAY more choices and way more sliders to adjust things.
If you already do. Try different face templates.
What I do is this:
I find a decent face template.
Then I go to the eye brows templates, I click through the different ones until I find one I like.
Or, that is easy to modify.
Then I do this with the eyes, nose(which there is only two that I like, maybe three), mouth, and chin. After that, I go to the third button. The one that allows you to adjust these "genetics".
I start with the actual face.
Moving the sliders back and forth through EACH one until I like it.
Then I move to the eyebrows, moving them up and down and thickening and thinning them
until its decent enough.
Same with eyes, nose, mouth, and chin.
Use different skintones too.
Different hairstyles, and different eyes from different creators.
Don't always use the same eyes. While I have some favorites too, and it is hard
not to use them, it's better to have variety.
Give some guys facial hair, a little or a lot.
Give some piercings, or even females some.
Mix and match make up too.
If you're a CC addict like me, there is a ton of accessories, and make-up on the internet
for you to use.
My favorites are:
Bruno - from MTS2
Icedmango or:
www.lapink.netShojoAngel - From MTS2
Hope this helps.
Remember -- to have patience, and just have fun.
Good luck with your Sims!
