4th time making sourdough and i’m really proud of:)

recipe:
100 g starter
250 g water
12 g salt
500 g bread flour

Process: Mixed water and starter, then added flour and salt, mixed until shaggy but no visible flour, let sit for an hour and did stretch folds, continued to do 3 more sets of stretch and folds every half hour or so. Total rising time including stretch and folds was about 8 hours. Shaped it after bulk ferment then let sit in a floured banneton for half an hour, then I covered it with a bag and let it ferment in the fridge overnight for about 13 hours. Preheated my dutch oven at 500°F for 40 mins, scored my dough and set it in the dutch oven with a couple of ice cubes. Let it bake at 450°F for 30 minutes covered, then 15 minutes uncovered.
