Whats wrong with my Sims3 graphics?

I've just installed some cool Mods stuff for my Sims 3 but my graphic are not as they used to. they're now horrible and blurry. they used to be more Deepened and Sharpened graphics with a great texture detail ( i have the graphic configuration of Sim at High and Texture Detail also high ) also some of the stuff i've installed like makeup or eyes doesn't appear when creating a Sim :( can someone help me tell me whats wrong and what can i do?
