Try as I might, I do not see Alix in Maria at all. In all her children her features mixed with others but still managed to "come victorious" somehow, but Maria, in my view, had nothing from her mother´s side at all. It was all Romanovs and Danish branch of the broad family in her face and body structure.
The more pictures of teenage and 1916-1918 Maria photos emerge, the more I see how distinct she was from her sisters (even Olga, though there was some resemblance there) and I hope some colour pictures will be found, because one can just sense how her natural colouring must have added to her loveliness (and her sisters too, naturally).
