Nasal bone on ultrasound

I know this might sound silly but, I'm currently 16 weeks pregnant and I had an ultrasound at 15 weeks, but it was a private ultrasound for a gender check, not at the doctors. I haven't been tested for downs or anything like that yet, so I'm worried about how my baby looks in the photos I got. I heard that a short or absent nasal bone can be a marker for downs. My baby's nose looks different than everyone else's ultrasound photos. I know the ultrasound technician was not even looking for that so maybe it just isn't a good photo, but I'm worrying myself! Does my baby's nasal bone look normal? In some of my photos I got it looks kind of small and cut off. Like the bottom two images.
