That looks very good indeed. There's a guide to bare metal finishes I posted some time ago, in the painting section, page 6 I think, which might give you some ideas for the future.
Just one point though. With bare metal finishes in particular (and most others) it's best to assemble the model first, before painting. That way, any filling or sanding of gaps, for example at wing roots, can be done and checked before painting. This is particularly important with bare metal, as any imperfections, however small, will show through the finish. And, of course, if the assembly is done after painting, then any remedial work will spoil the finish.
