Hi anthony, or possibly you may get better results building the whole entire thing out of one long sweep instead of trying to construct things in different separate sections like you are doing currently.

It is easier for one large sweep to be smooth throughout the interior parts of the sweep.

It's also easier for a large sweep to have a more gradual change from one shape to another, you've got too distinctly separate shapes and it will be hard to mask that by just trying to do a separate in between region.
