First loaf from my very first starter!

I got a sample of oregon trail starter mailed to me a few years ago and forgot about it. We recently moved across the country and I decided to give it a shot! This is my first bake after about 3 weeks of feeding it once a day. I was really impressed with how quickly the starter doubled and how short the proofing time ended up being.

I used the recipe from u/synster123's post about their absolutely gorgeous first loaf. Recipe is as follows:

• 350g King Arthur bread flour
• 270g water
• 70g starter
• 9g salt
• splash of olive oil

1. Add water, starter and mix until milky, then add flour and hand mix using the rubaud method until smooth
2. Add salt and olive oil, mix using rubaud method until smooth
3. Rest 45 minutes
4. Coil folds
5. Rest 45 minutes
6. Laminate
7. Rest 45 minutes
8. Coil folds
9. Rest 45 minutes
10. Coil folds
11. Bulk ferment (I used a chart to figure out the target rise based on my dough's temp)
12. Shape and place into banneton (or, if you're cheap like me, a plastic strainer lined with a flour-coated dish towel)
13. Cold ferment overnight, about 12 hours
14. Bake in a preheated dutch oven for 35 minutes covered at 475F, then uncovered at 420F until the color is nice (only took me about 5 minutes)
15. Cool on a wire rack until your wife wakes up and needs a piece of bread right now

I have a little bit of experience baking cookies and cupcakes, and I've messed around with a couple no-knead overnight loaves of bread, but this is my first time making bread that required me to actually get my hands dirty. I'm really pleased with how it came out! Please feel free to share any tips or critiques, even the pickiest little things. I'd love to get really good at this.
