That is a really fine model of the first version, F.1, of the Vampire:
I believe the illustration for the sharkmouth Vampire depicts the later FB5, with the lower stab and different fins. This is a more commonly modeled version, but I appreciate your modeling the F.1 version, since that is the one initially imported by the Swedish Air Force, while waiting for the SAAB J29 to be finished. Later on they ordered the FB5 version as well, but I like this early one.
For repainting purposes, do you draw your models in vector format, or pixel-based?
