It all really has to work together, you know what I mean.
But the first thing I look for is the face, specifically the eyes and lips. After that, I wants to see that big, beautiful round... personallity. Yeah. That's it. Personallity.
The first thing I notice is the face, but it doesn't matter how good her face looks if she doesn't have a nice ass. I can give up a little in the pretty face department, but I won't accept a sub par ass.
