Yeah, for example you've got a very slight dimple in the center there, which seems to me to be not a desired part of the intended design (although maybe I'm mistaken...).

What you should see tomorrow is that doing one sheet as the defining surface will make a kind of super smooth "idealized" quality to some of the parts like this.
