Here's an example using "Through points" instead, which can work pretty ok for tracing like this - it has a tendency to apply more force to the curve though and it's easy for there to be hooks and wiggles in the shape especially if your point set is sparse and if you make sudden changes in spacing. When you get to less detailed areas, don't just put a single point some far distance away from the tightly clustered ones, just gradually increase the distance to sort of ease-in/ease-out the distances rather than any sudden changes.

It tends to be easier to get a smooth result using control points, especially when you're freely drawing rather than tracing.

Anyway, here's what using "Through points" looks like:
