I don't get it. Half the features of the "small features" girl are actually large features and half the features of the "large features" girl are actually small features... I think you just mean large eyes vs small eyes. Both of them are gorgeous. Size of features aren't better over the other. It's all about balance.
I always liked large features, but I find myself liking the smaller features. You picked the wrong girl for smaller features since Emma has pretty big eyes in general - when she's not smiling... Kristen Bell is more of a small features girl:
