Second loaf

Toast

This is my second loaf and it looks okay but I feel the crumb could be improved, any tips? 

Hello, How old is your starter? i think more details might help? Looks kinda like my second loaf

 

Its possible that the starter is quite mature enough to be used to bake bread. Maybe add a bit of yeast if you really want bread.  or make bagels with it.  bagels are more forgiving.  they can be a little dense and still be good.  not that your bread isn't tasty.  my gummy sourdoughs still taste great
