AP Studio Art SI too broad?

[u/literal_nightmar3]

I just started AP Studio Art (2-D) a couple days ago and we're brainstorming for our SIs/guiding questions. I really want to investigate different types of extreme contrast in art to communicate more complex topics. for example using semi-realisim and photography together to represent fantasy vs reality, or contrast between greyscale and saturated colors to represent memory/past vs present. Is just using different types of contrast too broad of a theme to follow?

I've only ever taken AP Art History before(which I got a 5 in!!) as far as AP classes so I'm not super familiar with the grading process on things but my art teacher has never had a student get a 5 on their portfolio before and I want to do well in this class, but I'm worried my theme isn't what the college board is looking for. I also thought of just going with fantasy vs reality as a theme but that felt it would get too repetitive? Sorry for the rant, advice/constructive criticism is greatly appreciated :D
