I put the netwrok result on blue then showed where I deleted some surfaces and recreated them with a sweep.

I wont be able to help too much with this model, if you want to start to look at the tangent results of the surfaces.. You are modeling this by "patchwork" and although it can be done, it will be a more advanced/complex way to do it.. Basically, redoing many of your curves and an endless redo/fix scenario....
