You could try replacing half the formula’s water with scalded (and cooled) milk. Technically it is not a 1:1 exchange for water due to milk solids and fat but’s hardly worth differentiating for you one pizza. Yours looks nicely baked. Brown = flavor. Are you happy with the degree of browning on the crust and the toppings?
If there is not any sugar in your dough you could consider adding sugar in the amount of 2% of the flour’s weight. Same for oil. I’m guessing a forum recipe for pan pizza already called for both. Lastly, if you used oil in the pan try shortening next time. It will help your dough adhere to the pan (which does not look like something you had trouble with) and brown/caramelize differently than oil.
Really, more information is needed about the dough you made. A link to it? Length of time fermenting (rising) also contributes to flavor. How long from the time you finished mixing this dough until you baked it?
