Yes. it is. Though not so bad in the first 3/4s shot(still some horizontal lines bisecting her), the background in the second head+shoulders is really problematic--uneven separation between her hair and the dark background and odd shaped areas too close her head and torso. They pull your eye away--always my definition of "distracting."
I like the shots, but agree with CGW about the backgrounds.
And while it is important to be aware of the entire field of view, you do seem to have a good eye for the foreground, so there is lots of reason to keep experimenting.
After the "semester break" (which means no holidays) I will have more time and try to get some experiences in a professional photostudio. Here in Wuerzburg I can rent one. Then the distracting background shouldn't be a problem.
Sure, Wuerzburg is nice, and here are many places to take pictures from.
Klainmeister, did you worked there or were you on holiday?
