Did you use the templates from the following. http://www.norsewoodsmith.com/content/saw-filing-templates

There was a reason the old boys from yester year were artisans. Filing saws is an art that comes from lots of practice. The important part is does the saw cut wood smoothly now? You can work on refinement skills as you sharpen more saws. I have a couple beaters that I use to practice crosscut filing on, large teeth like 6-7 tpi. It’s easier to see what you are doing.
