A good start, but I think you should fair the frames more with straight lines - in the moment it just too round
In the moment you have them still too round - red (marked with red arrow) are the status in moment of your first frame
and they sghould be faired m,ore or less along the blue line
in the following photo are in red the faired line of the frames - green is the touching area of the final faired frame with the jig
so all frames should have contact with the jig along the green lines
