When looking at options ours were told to pick subjects they enjoyed, subjects relevant for any career choices, and subjects they were good at. ( I can't remember the exact order).
They were told not to pick subjects because a friend was, or they liked the teacher.
Bassd on the list it sounds as if your DC is on the creative side.
You have questioned not enough academics but the list includes tripple science. Also whilst there are a number of more practical/creative subjects in the list, I don't think you can say music isn't academic. ( they have to perform, compose and do a written exam).
Art and photography are both portfolio based, but there is more writing in art than you would think, because they need to write about artists they are studying, explain and critique things etc.
Just be careful with the amount of portfolio work in terms of time, and keeping on top of things. Depending on how the school works out options, I wouldn't be surprised at there being a few that choose both art and photography because they compliment each other. I know of a few in DC's friendship group that do both.
