Questions raised at pitch a plan

During pitch a plan the question of whether I wanted my work to be more expressive or subtle was raised , its hard to be sure at the moment as I feel I need to experiment more before I can give an answer. Initially I think I had envisioned my outcome being more expressive/ exaggerated but now I have started to experiment I think looking at more subtle outcomes is also interesting. I was also asked about what materials I planned on working with but again I am unsure as I don't know what I am going to be producing and I also want to experiment with different materials. In addition to that I plan to experiment with restriction, scale and weight and I'm not sure whether my work will be a response to just one or more of these areas.
