It's looking good there Andy.
One thing though - that part behind the radiator is the retractable boarding step. It was linked to the spring-loaded hand hold on the port side (the small rectangular 'panel', shown on the drawing, just aft of the cockpit), and should protrude from the outer edge of the fuselage, at the wing root, when in use.
If the step was extended, the hand hold cover, hinged at the top, would be open. If this was closed, then the step was retracted, flush with the fuselage, apart from a thin handle loop on the base of the step 'stirrup', not included on the kit part.
