That's very nice indeed. The only nit you could pick is the lack of intake splitter plates, and that'd be easy enough to fix.
Since F-105 kits mould the intakes as part of the wing, you could simply graft su-22 wings onto the Thud fuselage, then add the intakes of your choice and blend them in. They look Skyhawk-ish, but those would be way too small, unless you were willing to sacrifice a 1/48th Scooter for a 1/72nd model. Viggen ones would be around the right size for the engine, and old Airfix Viggens are cheap and easy to get.
