I think they go together really well.. Maybe you want to pick the two you think are best and place those on the left and right side of the abstract thing? Or put the three dance poses above or below the abstract thing looks good ^^ don't worry..
I know exactly what you mean with the anatomy studies instead of school work. I do way too much personal stuff compared to school stuff.. I try sometimes to keep a little connection with school stuff though, so that I can maybe show it at evaluations haha
