#12 and #13 are not even in the ballpark of what I am seeking. #"s 5 ,7, 9,10,14 are my favorites thus far but could you find a way to put a Music note or symbol to the design. Also love the colors blue and red representing arterial and venous blood ie, the Heart - Circulatory system.
Also # 1,2,3,4,11,12,13 can be omitted.
