to get a more accurate result, after i do birail or square operation, i insert a cople more Isos on the surface, then i select the Isos, then duplicate them as curves, then do a loft operation.
it always gives me gr8 results.
but from what i can see , your surface looks fine.

You want to make sure the curves that are opposite of each other have the same number of spans to get the cleanest result.

Yea, do what Mikey said. Before you birail it, rebuild the curves w/the same amount of spans. Thatll make ur mesh so much smoother. user added image

They cant, because of that double isosparm. Those being so close, means that theres uneven spans. But someone correct me if im wrong... user added image
