warm up- blackbird

So back to work after a fair time. My (wacom) pen was muzzled, as I couldn't really upload anything due to some confidentiality agreements. Just did this illutration of the Lockheed Blackbird to warm up!
I had the chance to see this plane in the flesh at Duxford, almost 4 years ago. There's something about this plane, that gives you a feeling that the perspective is wrong, no matter what angle you see it from!
