Tartine Oven Spring Improved!

After getting all of your super helpful feedback, I've decided to give the Tartine recipe another go.  I was having problems achieving a good spring: https://www.thefreshloaf.com/node/67063/oven-spring-help.  

See below for my latest.  I'm so happy with it!  Some changes I made:

• Knocked hydration down to 76% 
• Scored deeper and more to the center 
• Sprayed loaf with warm water (not sure if this did much) 

I'm pretty surprised at the outcome since I thought I butchered the dough during shaping. 

Thanks again for everyone's help here!
