One is not like the other

Jocelyn Allen is a photographer from Worcestershire college in England. She has been working on this project, One is not like the other. She creates these images with rather simple guidelines, but the outcome is interesting. I can't overlook the scientific application of her style. She photographs herself and family members in the same attire and location/pose. It is very matter of fact style photography. Allen's work reminds me of JeongMee Yoon's pink and blue project. They both use repetition to emphasize a single idea that pertains to a larger question. Variety and repetition meets harmony and solidarity. I would like to know what you all think about her photos.
