All projects need refinement, lightness, simplicity.
I tell my Mastery students often in a critique to lose 10% of their design. Sometimes 20%. Mass is not always required for strength. Careful engineering is required. Where can you remove material?
Adding lightness and simplicity is a difficult chore. How much work do you need to do to make something simple? How do you know what is unessential in a piece? Where do you stop?
Make copies. Make models, drawings. Try one thing and then another. Keep checking in with your gut to see how it feels. Keep practicing your paring skills. You will make mistakes. Try again.
