Dear Inger,
Thank you for the comforting comment. I deeply believe we should try to get below abstract models of QFT - search for internal structure and dynamics of particles: localized constructs of the field (solitons). Just repairing Maxwell's equations such that Gauss law no longer allows for any real charge, but only integer multiplicities of elementary ones as in the nature - e.g. by making that Gauss law counts topological charge like in Faber's approach. These elementary charges already became primitive electron models - now we need to expand the model to get all the particles and ellipsoid field is not only the only such expansion I could find, but surprisingly, while being extremely simple, it seems already qualitatively extremely promising - giving intuitive answers to many fundamental problems of physics ... as the right model should do.
However, while finding by simulations the proper form and constants of both potential and kinetic term of Lagrangian requires huge amount of work, it seems nobody is interested in understanding internal structure and dynamics of particles. And so I have to leave it for now, I'm starting information theory postdoc. But I would always gladly discuss about soliton particle model approaches.
Best regards,
