I am 50% Swedish and I have a very typical Swedish nose and face. I have studied features and can usually tell someones heritage just by looking at their face. First off, I have noticed that Swedes have a distinct type of nose. And I can tell just off the bat between two types. One, the light reflects off of the tip in an attractive way, also I can tell by the sides of the nose (lines go slighty up, in a soft way), and how the tip of the nose looks. Here are some examples:

The swedes usually have a very full, youthful face. The cheeks are usually very full.
