Nice work with Valiant. But I'd use less black on wings/engines and horizontal stabilizers - generally black is meant for sharp or near-sharp edges (I'd remove it from leading edges for example), and I'd try to work bit more on the canopy windows and tip of refueling probe.

Interesting work. Good to see a glider - there aren't many drawings around.
One suggestion (my personal mania
) - I'd make the lines of ailerons/flaps parallel to trailing edge of wings - right now they look like they have uneven width.
