Any flaws in my dome and arch design?

Hello
I am building a pizza oven and I want to know where I can buy a detail plan for that.
Can anyone help me please.
Thanks

Fornobravo sells some general plans for a small sum, but if you decide what size oven you want to build there are many threads on the forum that are detailed enough to follow along and build an oven.
