Nice, but I have some remarks:
1) minor - there are few pixels of contour missing here and there (maybe there is more of it, better check it);
2) serious one - I suspect that the source You were using was originally from some book or magazine, and it looks that the break of pages was going through the tailboom;
3) while unwritten, typically FD drawings show planes as in "horizontal flight" position, and Your Sea Vixen with undercarriage retracted (actually just erased) is actually "flying upwards";
4) I'd suggest working bit on shading, under the wings, for example.
