Looks good, except for the national markings on the fuselage. They look like they're floating as they lack any perspective deformation (should look a little squashed in height at the top and bottom where it curves with the fuselage) and the white of the bars on "Black George" should extend to the star's diameter. Please see attached.
The base shape of your Corsair looks pretty good. Most people forget the little hunchback behind the cockpit.
