I've seen Vulcans at air shows in Australia and New Zealand before they were decommissioned, they were pretty awesome rumbling overhead at low altitude, but never saw a Valiant or Victor. I agree with you that it's a particularly "pretty" plane for a military subject, and your model and render are lovely too. What drawings or data did you model it from, Colin? I grew up reading the Brit periodicals Aeromodeller and Scale Models, those titles both ran a set of drawings by a draftsman named Pat Lloyd, and I bought a set of his 1/72 versions from the publisher somewhere between thirty and forty years ago, still have 'em. They even had drawings of Britain's Blue Steel nuclear missile. I remember searching whether his drawings were still available more recently (well, probably more than a decade ago) and he had a web site and was selling them directly, but Google has buried that. Through Ron Moulton, the publisher of those magazines, Lloyd was also indirectly associated with the Gossamer Albatross project, the human-powered aircraft that won the Kremer prize for crossing the English Channel, which was another of his drafting subjects.
As an aside, I've read an analysis by an aero historian who contends that the UK surrendered the advantage it had from Whittle's invention of the jet engine. The Air Ministry more-or-less made it compulsory (ie by not financing other designs) to embed the engines in the wing roots like the V-bombers and the Comet airliner, instead of hanging them in pods off pylons like the US engineers' designs, which meant that they needed a lot more re-engineering to fit alternative engines. Probably not the whole story, but maybe a factor.
