The ghosting method has three stages to it. In the first one - the planning phase - we ask ourselves what a given mark is meant to contribute to our drawing, or to our understanding of how that construction exists in space. There are circumstances where a mark simply doesn't do much - for example, if you've got some contour lines on the surface of a form, adding another probably isn't going to help, and will instead add to the clutter.
Of course, if a mark helps us more precisely figure out the position of some element we wish to add, even if it is not a direct part of the object itself, then it is still of value and should still be added.
Don't think in terms of "too much construction" - just consider whether the elements you're building up could benefit from a little additional constructional information and support. If you can improve your precision a little more, if you can do something to make a curve just a little more specific and solid. These drawings are, as always, just exercises in spatial reasoning. Anything that helps you better understand the space in which you're working, and the way the object you're constructing occupies that space, is going to be valuable.
For what it's worth, you are faaar from putting in too much construction. You were in your submission skipping quite a few steps, so I would definitely err towards more construction rather than less.
