The design is far too fussy - although it's nice to see a couple of Gnats in the artwork.
The '50 Display Seasons' is so small that no-one will notice.
As has been said, too much of the saltire about it. The Hawk is an ugly, hunchbacked aeroplane lacking the Gnat's elegance - and that awful smoke pod is like a dog's dick. To improve the image, a simple design would have been preferable - this looks pretty dire, particularly with the stupid slanting font 'Royal Air Force' breaking the white lightning flash....
