Petals are hearts. Try different turn angles and % shrink. In real roses, successive petals turn at the golden angle, 137.5°. I think it looks best with turn angle set to the golden angle (137.5°), % shrink at 7%, darkening about 1%. Draw your own petal in remix.
Each rose uses heart shaped petals, copying, shrinking and turning that costume. This is from 2023 (Feb 24) which, in turn, I modified from my earlier rose project, but now using hearts.
