First Ever Focaccia

Toast

I am new to bread baking, came across Peter Reinhart BBA book and followed his instruction on cold retardation method for baking focaccia. It has a crispy top and soft centre. But I am not so sure how to judge a focaccia if it is a good one or average one. 

Can you please point me to the right direction?

but if you want it even more crispy, bake it more next time ;)
