Pernambuco (Brazil) [Independent]

Pernambuco is the 7th most populous and the 10th richest state of Brazi. I've been requested to design a set of flags for a hypothetical independent Pernambuco state. But today I'm only showing my solution for national land flag.

This is the current flag of Pernambuco:

















It's based in a flag used during a colonial rebellion:
















In the original flag, the three stars represent three capitanias (similar to a province) that adhered to rebellion: Pernambuco, Paraíba and Ceará. In current flag, the star represents statehood. The rest of symbolism is very obvious: white for peace, blue for sky, sun for energy and brightness, cross for faith, rainbow for plurality.

As I think the reference to statehood is not suitable for an independent country, I designed a new flag, but with links to the historical flag:

















I kept the rest of the symbols. Now without the star, I had to rebalance the flag, so I used the rainbow as a partition line, what would give room for both sun and cross and, as a side effect, fix green-blue contrast issue.

Comments and suggestions are welcome.
This flag was made under request. It's not intended as a political statement.
