Yes. I find Alix very similar to Tatiana in the pic you've posted above. However, I also find her very similar to Anastasia..But that's probably for Tatiana and Anastasia were somewhat related in facial features. Tatiana and Anastasia were similar , while Olga and Maria were also similar between them. As for Alexei, I think it was an interesting blend of Tatiana and Maria features.
