Thunderbird WIP

Something I've just roughed out for a story I wrote called The Shadows of the Sunless Sky. It's a transforming swept wing transport. In flight mode the wings are out and tail is vertical. In TAV (trans atmospheric vehicle) mode  the wings sweep back and tail rolls down to form a stealthy "black diamond". Still roughing out the main shapes but this is pretty close to my sketches so gonna start fine tuning and detailing

it out.
