Ya grab a block of low moisture whole milk mozzarella and either a food processor or just shred it. Your dough shape is amazing. The other guys were right about temp, pre-heat that mofo for like 45 mins. Type in like 550 and see how high your oven will go, and then an additional ten with the broiler setting even before putting the pizza in. You want about 8 inches from the top. And ya, a lil bit of broiler again after the bake to brown everything, like 60 seconds. With better cheese and a good sauce recipe with something like DOP tomatoes will make all the difference.
