It is not Christin Ludwig. She is the photographer. Her remark about the picture is "Good friend".
But she has some very nice black sleeves too:

And even more amazing her twin sister is also inked. Although the picture does not show too much ink.

The pics show a guy. So what? Christin Ludwig is a professional photographer as I pointed out two posts before and she is definitely a girl. Being a photographer she uses instagram to show her portfolio and these pics are in most cases no sefies, they show other people.
