We extend our recent numerical calculation of the pion electromagnetic form factor F{sub {pi}}(Q{sup 2}) in holographic QCD with a background field that interpolates between 'hard-wall' and 'soft-wall' models to obtain an improved model that reproduces the desirable phenomenological features of both. In all cases, F{sub {pi}}for large Q{sup 2} is shallower than data, an effect that can be cured by relaxing the fit to one of the static observables, particularly the decay constant f{sub {pi}}.
