Ballet dancer vs. hip hop dancer by Michelle Jia

What I observed that I think could be harmful:
The ballet dancers are majority white females, and the hip hop dancers are majority men/women of color it seems. (but honestly cannot tell too clearly because the images are so distorted. Also, it’s interesting that the backgrounds of these images are very much the same in each category.

Why I think this could be harmful, and to whom:
This is definitely stereotyping gender and race, which could be harmful to those not matching what these images depict.
