My first loaf

Hi everyone just baked my first sourdough loaf. My starter has been consistently tripling in size after feeding and I decided to bake my first loaf.
Recipe:
400 grams of bread flour
55 grams of whole wheat flour
10 grams of salt
345 grams of water
100 grams of starter
After mixing, for 4 hours I did stretch and folds each hour at room temperature, (so four series of stretch and folds 4 times )i shaped it, then did a cold proof in the fridge for 10 hours. After the cold proof I baked at 230 celsius for 20 minutes covered and then 20 uncovered. It was baked in a preheated dutch oven. Cooled it for 40 minutes. Appreciate the feedback. Thanks everyone. 😊
